Hi. This is my first post on the forums.

I am trying to write a script that will parse a folder of files "oneverylongfilenamexyz.pdf" and create a .dat file named "oneverylongfilenamexyz.dat" with the first line of each .dat file saying variable="xyz" where xyz is the last 14 characters of $i before the extension.

My syntax is very poor but I think the logic should be something like

# first loop to make dat files
for i in `ls -R dat_tmp/ | grep .pdf`
touch $i.dat
# second loop to fill dat files
for i in `ls -l | grep .dat`
echo 'variable=`sed[last 14 characters] $i`' > $i.dat


Any help is much appreciated. Thank you.
