Daniel Tameling <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #9 from Daniel Tameling <[email protected]> --- (In reply to Craig Leres from comment #5) I don't think it is a good idea to remove the -f flag from the wrapper script. Quoting the xz man page: "When used with --decompress --stdout and xz cannot recognize the type of the source file, copy the source file as is to standard output. This allows xzcat --force to be used like cat(1) for files that have not been compressed with xz." So currently you can search normal files simultaneously with xz archives with a single command. E.g. if one uses xz to compress /var/log/messages one can use xzgrep harfbuzz /var/log/messages* to search all files. Without the flag one would get the warnings for the non-xz files, but they wouldn't be passed to stdout. The upstream xzgrep file also uses the -f flag, so changing it in base would reduce the portability of scripts. However, upstream has a way to deal with the situation: it invokes other programs, depending on the file ending: case $i in *[-.][zZ] | *_z | *[-.]gz | *.t[ag]z) uncompress="gzip -cdf";; *[-.]bz2 | *[-.]tbz | *.tbz2) uncompress="bzip2 -cdf";; *[-.]lzo | *[-.]tzo) uncompress="lzop -cdf";; *[-.]zst | *[-.]tzst) uncompress="zstd -cdfq";; # zstd needs -q. *[-.]lz4) uncompress="lz4 -cdf";; *) uncompress="$xz -cdfqQ";; # -qQ to ignore warnings like unsupp. check. esac Something similar could be implemented in our wrapper script if one really wants to address the issue. -- You are receiving this mail because: You are the assignee for the bug.
