| Pack is a simple version of the traditional Unix ar tool. | |
| It implements only the operations needed by Go. | |
| Usage: | |
| go tool pack op file.a [name...] | |
| Pack applies the operation to the archive, using the names as arguments to the operation. | |
| The operation op is given by one of these letters: | |
| c append files (from the file system) to a new archive | |
| p print files from the archive | |
| r append files (from the file system) to the archive | |
| t list files from the archive | |
| x extract files from the archive | |
| The archive argument to the c command must be non-existent or a | |
| valid archive file, which will be cleared before adding new entries. It | |
| is an error if the file exists but is not an archive. | |
| For the p, t, and x commands, listing no names on the command line | |
| causes the operation to apply to all files in the archive. | |
| In contrast to Unix ar, the r operation always appends to the archive, | |
| even if a file with the given name already exists in the archive. In this way | |
| pack's r operation is more like Unix ar's rq operation. | |
| Adding the letter v to an operation, as in pv or rv, enables verbose operation: | |
| For the c and r commands, names are printed as files are added. | |
| For the p command, each file is prefixed by the name on a line by itself. | |
| For the t command, the listing includes additional file metadata. | |
| For the x command, names are printed as files are extracted. | |
