Code:

awk '{print $1}' <1.txt

when I run this
#!/bin/sh
for line in `cat 1.txt`
do
#echo "$line"
echo awk `{print $1}` < 1.txt
done
it gives me
apple
orange
juice
table
etc.

But I need only
apple
table
tea
bed ;(

try:

Code:

#!/bin/sh
 
while read a b
do
   echo $a
done < 1.txt

Did you check joeyg's post - #3

You just need to run a single line awk program:

Code:

awk '{print $1}' 1.txt

If you do not mind can explain why a b? what does it mean???? sorry, i am new in shell....P.S. it works btw, I just want to understand. Thank you for helping
