Top Forums UNIX for Beginners Questions & Answers Issue with cat command on a for loop Post 303037997 by MadeInGermany on Tuesday 20th of August 2019 12:41:06 PM

This is because the for list splits on IFS that defaults to space,tab,NL.
So a space is treated like a NL.
You can explicitly set IFS to only NL
Code:
# subshell starts
(
# split on NL only
IFS="
"
for TESTING in $(cat TEST.tmp); do echo "$TESTING"; done
)
# subshell ended, IFS is default again.

But it is more clever to use read that reads lines
Code:
while read line
do
  echo "$line"
done < TEST.tmp

And it splits into distinct variables by IFS (space and tabs only; it will never see an NL because of the read)
Code:
while read word1 word2
do
  echo "word1=$word1 word2=$word2"
done < TEST.tmp
