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.
