Zutils is a collection of utilities able to deal with any combination of
|
|
compressed and uncompressed files transparently. If any given file,
|
|
including standard input, is compressed, its decompressed content is
|
|
used. Compressed files are decompressed on the fly; no temporary files
|
|
are created.
|
|
|
|
These utilities are not wrapper scripts but safer and more efficient C++
|
|
programs. In particular the "--recursive" option is very efficient in
|
|
those utilities supporting it.
|
|
|
|
The provided utilities are zcat, zcmp, zdiff, zgrep, ztest and zupdate.
|
|
The supported formats are bzip2, gzip, lzip and xz.
|
|
The compressor to be used for each format is configurable at runtime.
|
|
|
|
Zcat, zcmp, zdiff, and zgrep are improved replacements for the shell
|
|
scripts provided by GNU gzip. Ztest is unique to zutils. Zupdate is
|
|
similar to gzip's znew.
|
|
|
|
NOTE: Bzip2 and lzip provide well-defined values of exit status, which
|
|
makes them safe to use with zutils. Gzip and xz may return ambiguous
|
|
warning values, making them less reliable back ends for zutils.
|
|
|
|
LANGUAGE NOTE: Uncompressed = not compressed = plain data; it may never
|
|
have been compressed. Decompressed is used to refer to data which has
|
|
undergone the process of decompression.
