how to get the filename from the mentioned list - linux

Question

I am new to linux and/or scripting, so bear with me. I want a script which can get the files for a Linux directory. here what I tried for getting the filename.
for NAME in $(ls -1 *.wav /some/path | cut -d "/" -f3 | cut -d "-" -f1-5)
if the filename contains -IN or -OUT then they will be sox -m and after that mv to another directory but if the some other files then it will be just mv
for the reference, filenames be like
1030-04-06-2015-1433414216.wav
1030-04-06-2015-1433414318.wav

Answer 1

This should work:
#!/bin/bash
regex='(.*)(-out|-in)(.txt)'
for file in *.txt;do
# $file is the full path to the file
if [[ $file =~ $regex ]];then
#filename in this block contains -in or -out
filename="${file##*\/}"
inorout="${BASH_REMATCH[2]}"
extension="${BASH_REMATCH[3]}"
filenamewithoutextension="${filename%.*}"
filenamewithoutioroutorextension="${filenamewithoutextension/%$inorout/}"
filenamewithoutiorout="${filenamewithoutioroutorextension}$extension"
echo "$filename" "$inorout" "$extension" "$filenamewithoutextension" "$filenamewithoutiorout" "$filenamewithoutioroutorextension"
#do something here sox-m mv or whatever
else
#filename in this block doesn't contain -in or -out
echo "do something else"
fi
done
Explanation:
"${file##*\/}" is the string left by cutting */ from $file i.e the basename (filename).
"${BASH_REMATCH[2]}" is the second captured group from the pattern matching done by [[ $file =~ $regex ]] i.e -in or -out
"${BASH_REMATCH[3]}" is the third captured group i.e .wav.
"${filename%.*}" is the string left by cutting .* from $file i.e filename without .wav

Answer 2

Here is one way to do it.
>cat test.sh
#!/bin/bash
destination="./DEST"
# Loop over every file
for file in "${#}" ; do
# If it is "-in", then sox
if [[ "${file}" =~ "-in" ]] || [[ "${file}" =~ "-out" ]] ; then
printf "sox -m ${file}; "
fi
echo "mv ${file} ${destination}"
done
When run, I get the following output.

If you want to execute the commands, simply cut and paste these lines into a shell, or modify the bash script to execute these commands rather than print them.
