Question

thanks for reading & your suggestions. I’m moving files into respective directories, only some of the files use _ and some use - (underscore and hyphen) as delimiters. Is there a way to test for the different delimiters?

E.g.:

ParentDir
    1897/
    1898/
    1994summer/
    file-1897-001.txt
    file-1897-002.txt
    file-1898-001.txt
    file-1898-002.txt
    file_1994summer_001.txt
    file_1994summer_002.txt

I’ve been processing with the following (verbose so I can understand it) shell script:

!/bin/sh
for f in *.jp2
do
base=${f%.txt}
echo "base fileName is $base"
fileName=`echo "$base" | cut -f 2 -d _`
echo "truncated fileName is $fileName"
dir=$fileName
echo "Directory is $dir"
mv -v "$f" "$dir"
sleep 1
done

When using the cut command, I’d like to be able to differentiate on the delimiter. Is that possible? Thanks in advance for your time & suggestions.
Cheers!

Answer 1

case "${fName}" in 
    *_* ) underscore_funnyFace_processing "${fName}" ;; 
    *-* ) hyphen_funnyFace_process "${fName}" ;; 
    * ) all_other_processing "${fName}" ;; 
esac

I’m almost sure bourne shell supported case processing. Don’t have access to one to test with.

The difference between bourne/bash/ksh/zsh would be in the shell wildcards patterns that each shell has as an extension to the basic patterns the bourne shell supported.

I hope this helps.
