I tested bash string replacement in Fedora 14 (bash-4.1.7-4.fc14.x86_64). It works fine:
$ AAA='/a/b/c/путь'
$ echo ${AAA//?/.}
...........
So looks like this is BASH ISSUE.
Works for me:
$ AAA='/a/b/c/путь'
$ echo ${AAA//?/.}
...........
$ rpm -q bash
bash-4.2.20-1.fc16.x86_64

Description of problem: I use cdargs since Fedora 10 or even maybe earlier. It always worked fine for me, but it got broken in Fedora 16. I use russian locale and my home doc/ video/ etc. directories have russian names: Документы/, Видео/ etc. I use cdargs to say just, for example, 'cv docs/' to cd to Документы/. Since Fedora 16 i get error messages like following when using bash completion with tabs: cv docs/sed: -e выражение #1, символ 10: неизвестный модификатор к `s' sed: -e выражение #1, символ 10: неизвестный модификатор к `s' sed: -e выражение #1, символ 10: неизвестный модификатор к `s' Same 3 lines in Russian are result of triple key Tab pressing. They say: sed: -e expression #1, symbol 10: unknown modifier to 's'. After some investigation i found that problem is in file /etc/profile.d/cdargs.sh in function _cdargs_aliases() in the line where variable $strip is created: strip="${dir//?/.}" then it is used in lines: COMPREPLY=( $( compgen -d "$dir`echo "$cur" | sed 's#^[^/]*##'`" \ | sed -e "s/^$strip/$bookmark/" -e "s/\([^\/a-zA-Z0-9#%_+\\\\,.-]\)/\\\\\\1/g" ) ) The author's original idea was to change all symbols in $dir by dots ('.'). This really works when all symbols are english, here are examples from my bash: $ AAA='/a/b/c' $ echo ${AAA//?/.} ...... But in my bash (bash-4.2.20-1.fc16.x86_64) it does not work with russian symbols: $ AAA='/a/b/c/путь' $ echo ${AAA//?/.} /a/b/c/путь You can see that bash's string replacement operator just does nothing! So, PROBABLY THIS IS BASH ISSUE, i do not know the meanings of '?' here well. Then the error messages of sed are obvious: it just tries to replace something like s//a/b/c/путь/$bookmark/ Also simple solution: strip=$(echo $dir | sed 's/././g') instead original line strip="${dir//?/.}" works fine because sed's 'dot' regexp matches russian (UTF-8) characters.
