I have a script and i'm using this to find and list files that end with .txt in the tmp folder
find /tmp -type f \( -name '*.txt' \) |cut -c14-
The output is something like this:
xpto.txt
abc.txt
xyz.txt
But i want to add an index at the beggining of each line
1 - xpto.txt
2 - abc.txt
3 - xyz.txt
Can anyone help me? i'm still learning bash, started 1 month ago.
You could do:
find /tmp -type f \( -name '*.txt' \) |cut -c14- | nl
But the find command does not always works very friendly with pipes in my experience.
so you could do also this:
cd /tmp ; ls *.txt | nl
or this (for a different output layout)
cd /tmp ; ls *.txt | grep -n ""
find will also list files that are in a subdirectory, while ls won't.
find however,the cut command also needs some tinkering to let it work. Also he will probably need xargs to process the output of find further. No harm in trying different approaches :-)Try piping command output to following awk
awk -v OFS="-" '{print NR, $0}'
perl variant
perl -lne 'print $.,"-",$_'
man nl
