Hello list!
Using GNU tar 1.19, I was unable to extract files from a tar
archive using wildcards when the file name contains a byte
sequence that is not valid in the current locale. Specifically,
this didn't work as I expected:
$ touch $(echo -en 'file-\0344')
$ tar -vcf my.tar file-*
file-\344
$ tar -tf my.tar
file-\344
$ tar -tf my.tar --wildcards '*'
tar: *: Not found in archive
tar: Error exit delayed from previous errors
$ LC_CTYPE=C tar -tf my.tar --wildcards '*'
file-\344
The byte \344 is the character 'รค' ('a' with umlauts) in latin1.
The files in my archive came from a system with a different
encoding. But regardless of the file names in the archive not
matching the system's encoding, I would still expect the pattern
'*' to match all files.
This can be very annoying when the pattern doesn't fail entirely,
for example, the following command may silently fail to extract
some of the files:
$ tar -xf my.tar --wildcards --wildcards-match-slash 'sub/dir/*'
As a work-around, setting LC_CTYPE=C seems to make it work.
Thanks,
