Hi:

One way:

#!/usr/bin/sh
while read LINE
do
X=$(echo ${LINE}|tr -d " ")
echo "this is the line: ${X}"
done < temp1/${a}

Regards!

>how can I delete the space

If you want to do other changes, you can modify JRF's solution to use sed(1):
while read LINE; do
X=$(echo ${LINE} | sed -e 's/ //g')
echo "this is the line: ${X}"
done < temp1/${a}

Or change Raj's to remove that evil cat:
for x in $(tr -d " " < temp1.${a}); do

Note if there are other whitespaces in the lines, each $x will not contain the whole line.

Thx Dennis, for puting the evil cat under subshell parenthesis , to parse it corrctly.

(0 or 1 pts. only pls. )
