I have a text file that holds a list of files. I want to cat
their contents together. What is the best way to do this? I was doing something like this but it seems overly complex:
let count=0
while read -r LINE
do
[[ "$line" =~ ^#.*$ ]] && continue
if [ $count -ne 0 ] ; then
file="$LINE"
while read PLINE
do
echo $PLINE | cat - myfilejs > /tmp/out && mv /tmp/out myfile.js
done < $file
fi
let count++
done < tmp
I was skipping commented lines and running into issues. There has to be a better way to do this, without two loops. Thanks!
Or in a simple command
cat $(grep -v '^#' files) > output
