| At least one command option or a PROGRAM is required, as shown above. |
|
|
| PROGRAM list library (DLL) dependencies of PROGRAM |
| -c, --check-setup show installed version of PACKAGE and verify integrity |
| (or for all installed packages if none specified) |
| -d, --dump-only do not verify packages (with -c) |
| -n, --names-only just list package names (implies -c -d) |
| -s, --sysinfo produce diagnostic system information (implies -c -d) |
| -r, --registry also scan registry for Cygwin settings (with -s) |
| -k, --keycheck perform a keyboard check session (must be run from a |
| plain console only, not from a pty/rxvt/xterm) |
| -e, --search-package list all available packages matching PATTERN |
| PATTERN is a glob pattern with * and ? as wildcard chars |
| search selection specifiers (multiple allowed): |
| --requires list packages depending on packages matching PATTERN |
| --build-reqs list packages depending on packages matching PATTERN |
| when building these packages |
| only the most recent available releases are checked |
| to collect requirements info |
| -i, --info-package print full info on packages matching PATTERN, installed |
| and available releases |
| PATTERN is a glob pattern with * and ? as wildcard chars |
| info selection specifiers (multiple allowed): |
| --inst only print info on installed package release |
| --curr only print info on most recent available release |
| --prev only print info on older, still available releases |
| --test only print info on test releases |
| --deps additionally print package dependencies |
| --build-deps additionally print package build dependencies |
| -f, --find-package find the package to which FILE belongs |
| -l, --list-package list contents of PACKAGE (or all packages if none given) |
| -p, --package-query search for REGEXP in the entire cygwin.com package |
| repository (requires internet connectivity) |
| --delete-orphaned-installation-keys |
| Delete installation keys of old, now unused |
| installations from the registry. Requires the right |
| to change the registry. |
| -v, --verbose produce more verbose output |
| -h, --help annotate output with explanatory comments when given |
| with another command, otherwise print this help |
| -V, --version print the version of cygcheck and exit |
|
|
| Notes: |
| -c, -f, and -l only report on packages that are currently installed. |
| -i and -e report on available packages, too. To search for files within |
| uninstalled Cygwin packages, use -p. The -p REGEXP matches package names, |
| descriptions, and names of files/paths within all packages. |
| </pre></div><div class="refsect1"><a name="cygcheck-desc"></a><h2>Description</h2><p> The <span class="command"><strong>cygcheck</strong></span> program is a diagnostic utility for |
| dealing with Cygwin programs. If you are familiar with |
| <span class="command"><strong>dpkg</strong></span> or <span class="command"><strong>rpm</strong></span>, |
| <span class="command"><strong>cygcheck</strong></span> is similar in many ways. (The major |
| difference is that <span class="command"><strong>setup</strong></span> handles installing and |
| uninstalling packages; see <a class="xref" href="setup-net.html#internet-setup" title="Internet Setup">the section called “Internet Setup”</a> for more |
| information.) </p><p> The <code class="literal">-c</code> option checks the version and status of |
| installed Cygwin packages. If you specify one or more package names, |
| <span class="command"><strong>cygcheck</strong></span> will limit its output to those packages, or |
| with no arguments it lists all packages. A package will be marked |
| <code class="literal">Incomplete</code> if files originally installed are no longer |
| present. The best thing to do in that situation is reinstall the package |
| with <span class="command"><strong>setup</strong></span>. To see which files are missing, use |
| the <code class="literal">-v</code> option. If you do not need to know the status |
| of each package and want <span class="command"><strong>cygcheck</strong></span> to run faster, add |
| the <code class="literal">-d</code> option and <span class="command"><strong>cygcheck</strong></span> will |
| only output the name and version for each package. Add the |
| <code class="literal">-n</code> option to output only the names of packages. </p><p> If you list one or more programs on the command line, |
| <span class="command"><strong>cygcheck</strong></span> will diagnose the runtime environment of that |
| program or programs, providing the names of DLL files on which the |
| program depends. If you specify the <code class="literal">-s</code> option, |
| <span class="command"><strong>cygcheck</strong></span> will give general system information. If you |
| list one or more programs on the command line and specify |
| <code class="literal">-s</code>, <span class="command"><strong>cygcheck</strong></span> will report on |
| both.</p><p> The <code class="literal">-e</code> option allows to seach for available |
| packages in the Cygwin distribution. <code class="literal">PATTERN</code> is |
| a glob pattern, using * and ? as wildcard characters, just as in |
| filename patterns. <code class="literal">PATTERN</code> is searched for in |
| the package name and the summary of a package. |
| The <code class="literal">--requires</code> and <code class="literal">--build-reqs</code> |
| options allow to search for packages which have a certain dependency, |
| either at runtime or at build time.</p><p> The <code class="literal">-i</code> option prints a lot of information |
| available for installed packages, as well as for available packages |
| in the Cygwin distribution. <code class="literal">PATTERN</code> is a glob |
| pattern, using * and ? as wildcard characters, just as in filename |
| patterns. <code class="literal">PATTERN</code> is compared against the |
| package name as well as against the combined package name and version. |
| With additional info selectors, <code class="literal">--inst</code>, |
| <code class="literal">--curr</code>, <code class="literal">--prev</code>, and |
| <code class="literal">--test</code>, allow to specify that only information |
| in terms of installed, current latest available, older available, |
| as well as test packages respectively, is requested. |
| The <code class="literal">--deps</code> and <code class="literal">--build-deps</code> |
| options allow to print additional dependency information.</p><div class="example"><a name="utils-cygcheck-eiex"></a><p class="title"><b>Example 3.4. Example <span class="command">cygcheck</span> -e/-i |

| Name : grep |
| Version : 3.8 |
| Release : 2 |
| Architecture: x86_64 |
| Size : 401340 (392 K) |
| Source : grep-3.8-2-src.tar.xz |

| Summary : search for regular expression matches in text files |
| Description : |
| GNU grep searches one or more input files for lines containing a |

| options fetch info from a distribution db file. This file will be |
| downloading on demand and refreshed if it's older than 24 hours.</p><p> The <code class="literal">-f</code> option helps you to track down which |
| package a file came from, and <code class="literal">-l</code> lists all files in a |
| package. For example, to find out about |
| <code class="filename">/usr/bin/less</code> and its package: |
| </p><div class="example"><a name="utils-cygcheck-ex"></a><p class="title"><b>Example 3.5. Example <span class="command">cygcheck</span> -f/-l |

| /usr/bin/lessecho.exe |
| /usr/bin/lesskey.exe |
| /usr/man/man1/less.1 |
| /usr/man/man1/lesskey.1 |
| </pre></div></div><br class="example-break"><p>The <code class="literal">-h</code> option prints additional helpful messages |
| in the report, at the beginning of each section. It also adds table |
| column headings. While this is useful information, it also adds some to |
| the size of the report, so if you want a compact report or if you know |
| what everything is already, just leave this out.</p><p>The <code class="literal">-v</code> option causes the output to be more |
| verbose. What this means is that additional information will be reported |
| which is usually not interesting, such as the internal version numbers of |
| DLLs, additional information about recursive DLL usage, and if a file in |
| one directory in the PATH also occurs in other directories on the PATH. </p><p>The <code class="literal">-r</code> option causes <span class="command"><strong>cygcheck</strong></span> |
| to search your registry for information that is relevant to Cygwin |
| programs. These registry entries are the ones that have "Cygwin" in the |
| name. If you are paranoid about privacy, you may remove information from |
| this report, but please keep in mind that doing so makes it harder to |
| diagnose your problems.</p><p>In contrast to the other options that search the packages that are |
| installed on your local system, the <code class="literal">-p</code> option can be |
| used to search the entire official Cygwin package repository. It takes as |
| argument a Perl-compatible regular expression which is used to match |
| package names, package descriptions, and path/filenames of the contents |
| of packages. This feature requires an active internet connection, since |
| it must query the <code class="literal">cygwin.com</code> web site. In fact, it is |
| equivalent to the search that is available on the <a class="ulink" href="https://cygwin.com/packages/" target="_top">Cygwin package listing</a> |
| page.</p><p>For example, perhaps you are getting an error because you are missing |
| a certain DLL and you want to know which package includes that file: |
| </p><div class="example"><a name="utils-search-ex"></a><p class="title"><b>Example 3.6. Searching all packages for a |
| file</b></p><div class="example-contents"><pre class="screen"> |

| coreutils-5.2.1-5 GNU core utilities (includes fileutils, sh-utils and textutils) |
| coreutils-5.3.0-6 GNU core utilities (includes fileutils, sh-utils and textutils) |
| </pre></div></div><br class="example-break"><p>Note that this option takes a regular expression, not a glob or |
| wildcard. This means that you need to use <code class="literal">.*</code> if you |
| want something similar to the wildcard <code class="literal">*</code> commonly used |
| in filename globbing. Similarly, to match the period character you should |
| use <code class="literal">\.</code> since the <code class="literal">.</code> character in a |
| regexp is a metacharacter that will match any character. Also be aware |
| that the characters such as <code class="literal">\</code> and <code class="literal">*</code> |
| are shell metacharacters, so they must be either escaped or quoted, as in |
| the example above.</p><p>The third example above illustrates that if you want to match a whole |
| filename, you should include the <code class="literal">/</code> path seperator. In |
| the given example this ensures that filenames that happen to end in |
| <code class="literal">ls.exe</code> such as <code class="literal">ncftpls.exe</code> are not |
| shown. Note that this use does not mean "look for packages with |
| <code class="literal">ls</code> in the root directory," since the |
| <code class="literal">/</code> can match anywhere in the path. It's just there to |
| anchor the match so that it matches a full filename.</p><p>By default the matching is case-sensitive. To get a case insensitive |
| match, begin your regexp with <code class="literal">(?i)</code> which is a |
| PCRE-specific feature. For complete documentation on Perl-compatible |
| regular expression syntax and options, read the <span class="command"><strong>perlre</strong></span> |
| manpage, or one of many websites such as <code class="literal">perldoc.com</code> |
| that document the Perl language.</p><p>The <span class="command"><strong>cygcheck</strong></span> program should be used to send |
| information about your system for troubleshooting when requested. When |
| asked to run this command save the output so that you can email it, for |
| example:</p><pre class="screen"> |
| <code class="prompt">$</code> <strong class="userinput"><code>cygcheck -s -v -r -h > cygcheck_output.txt</code></strong> |
| </pre><p> Each Cygwin DLL stores its path and installation key in the |
| registry. This allows troubleshooting of problems which could be a result |
| of having multiple concurrent Cygwin installations. However, if you're |
| experimenting a lot with different Cygwin installation paths, your |
| registry could accumulate a lot of old Cygwin installation entries for |
| which the installation doesn't exist anymore. To get rid of these |
| orphaned registry entries, use the <span class="command"><strong>cygcheck |
| --delete-orphaned-installation-keys</strong></span> command.</p></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="chattr.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="using-utils.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="cygpath.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">chattr </td><td width="20%" align="center"><a accesskey="h" href="cygwin-ug-net.html">Home</a></td><td width="40%" align="right" valign="top"> cygpath</td></tr></table></div></body></html> |
