Check a specific word whether is in file
I want to valid a specific word whether it is contained in the text file. For example:

family.txt
father
mother
son
sister
Code:
if ("father" contain in family.txt)
     do some process
else
    do other process

How shell scripting can accomplish this? Anyone can provide helps?

Hi dude,


Quote:
#/bin/bash
cat family.txt | grep father
s=`echo $?`
if [ $s = 1 ]
then
echo "the command is correct"
else
echo "the command is not correct"
fi
With Regards
