I have a need to pass a script to a perl script to run in some directories in linux (ubuntu) with bash --version GNU bash, versión 4.4.20(1)-release (x86_64-redhat-linux-gnu)

These directories have a problem, and that is that they have extended characters including spaces, and local language characters.

IFS=$'\n'
for dir in $(ls -1ld  /home/setdart/mail/setdart.com/albertit/{.,?}*/ | tr '\n' '\0' | xargs -0 -n 1 basename); do echo "$dir"; done > albertit.txt

Which gives me

Files containing &AO8, &AO0- are not processed by the second command, they are actually extended characters of the language

for file in $(cat albertit.txt); do echo "$file"; tools/maildir-size-fix.pl -a -f -c -r $file; done

I can't find a solution and I have more than 100 users in whom I have to pass the script and all of them, being Catalan, use Catalan as the language to name their folders.

I don't know how to proceed to do it.

CodePudding user response：

• do not parse ls https://unix.stackexchange.com/questions/128985/why-not-parse-ls-and-what-to-do-instead
• for i in $(..) is an antipattern. https://mywiki.wooledge.org/BashFAQ/001
• for i in $(command); do echo $i Just execute the command, why loop with echo. It already echoes.
• check your scripts with shellcheck !
• | tr '\0' '\n' | xargs -0 does not add any security. Just | xargs -d '\n' then, newlines are going to hurt anyway.

I could see something along:

printf "%s\0" /home/setdart/mail/setdart.com/albertit/{.,?}*/ | xargs -0 basename -z -a > albertit.txt

Or I think just:

find /home/setdart/mail/setdart.com/albertit/ -maxdepth 1 -mindepth 1 -type d -printf "%f\0" > albertit.txt

And then:

while IFS= read -r -d '' file; do
   echo "$file"
   tools/maildir-size-fix.pl -a -f -c -r "$file"
done < albertit.txt

But then just:

xargs -0 -n 1 tools/maildir-size-fix.pl -a -f -c -r < albertit.txt

CodePudding user response：

Generally, the simple construct of

for dir in /home/setdart/mail/setdart.com/albertit/{.,?}*/
do tools/maildir-size-fix.pl -a -f -c -r "$dir"
done

really should work, even with odd characters.
Does it not? Did you quote it?

If it doesn't, what does it do?
