Process each line of a file in bash
Solution 1:
You don't need to use cat:
while read line; do
echo "$line"
done < my_file
I don't think there's a simpler way though.
Solution 2:
The simplest, I think, would be to use xargs, e.g.,
xargs -L1 gzip < my_file
The -L1 option tells xargs to process one input line at a time. You might take a look at GNU parallel, too, which is very similar to xargs but more powerful in some situations.
Solution 3:
IFS="\n\b"; for i in $MYROWOFCONTENT; do echo $i; done;
