Just a guess... '\b' is a valid escape sequence (backspace, or 0x08 in ASCII). None of the other characters after '\'s are valid escape sequences. Therefore it looks like 'tar' treats '\' followed by a character as an escape sequence if it recognizes it, otherwise it treats it literally. The other solution would be to use a sed script to double the '\'s, but as you observed, using POSIX paths would be better. I forget if '-T -' is valid; if it is, you could do something like: cat file_list.txt | xargs -n 1 cygpath -u | tar args -T - args -- Matthew Ok, so the quotes aren't entirely original. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

It's certainly not the highest priority on my list. I would just stick with POSIX paths.

tar, win-path conversion bug
I think I've run into a bug concerning tar and the use of windows format paths. It's not a bug that is difficult to work around, but it still seems as though it is a bug that someone may wish to address (in their spare time, of course :-). I wanted to save a list of files into a tar archive where the list was created by a windows-based utility that generated windows-style pathnames. Just to see if it was supported at all, I decided to try it with 1 file first, before attempting the whole archive. Created file /tmp/tst that contained 1 filename: c:\WINDOWS\msagent\chars\brocklee.acs My command line was: tar cvpf /tmp/tst.tar -T /tmp/tst --ignore-case --no-recursion My output was: tar: Removing leading `c:\' from member names tar: c\:\\WINDOWS\\msagent\\chars\brocklee.acs: Cannot stat: No such file or directory tar: Substituting `.' for empty member name tar: : Cannot stat: No such file or directory tar: Error exit delayed from previous errors ls gives: ls -lGg C:\\Windows\\msagent\\chars\\brocklee.acs -rw-r- 1 3614596 Jul 5 2002 C:\Windows\msagent\chars\brocklee.acs Note in tar, the backslash before the filename wasn't doubled as were the other backslashes: tar: c\:\\WINDOWS\\msagent\\chars\brocklee.acs ^^ If I edit the input file and add an extra backslash before the filename, like: c:\WINDOWS\msagent\chars\\brocklee.acs ^ extra backslash Then tar works. Easy workaround is to convert the paths to unix-type paths. -linda -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
