UNIX for Dummies Questions & Answers

Hi Jimmy,

All you need to do is remove the line 'echo $name found in file2'.

I left both 'found' and 'not found' in just so you can see how the logic works.

If you have any questions about the logic, drop me a line.

Cheers
Helen

I'm sorry to make you hold my hand but I'm really not proficient with this stuff. This is what I've done but it's still not giving me the desired output:

while read name
do
found="no"
while read line
do
echo $line | grep $file1 >/dev/null
if [ $? -eq 0 ]
then
found="yes"
break
fi
done < file2
if [ $found = "no" ]
then
echo $name not found in file2
fi
done < file1

You need to change the line:

echo $line | grep $file1 >/dev/null

to

echo $line | grep $name >/dev/null


It was just a bit of a typo, thats all!

Cheers
Helen

Hello Helen,

It still doesn't seem to be working and now I'm getting Usage: grep -hblcnsviw patternfile messages like crazy. If you're getting tired of responding to this,let me know and I'll drop it and try to find the answer some other way.

while read name
do
found="no"
while read line
do
echo $line | grep $name >/dev/null
if [ $? -eq 0 ]
then
found="yes"
break
fi
done < file2
if [ $found = "no" ]
then
echo $name not found in file2
fi
done < file1

Helen, are you in the US?

I tried to send you an email directly, but you have the facility switched off.

It would be easier for me to contact you directly - it would save me constantly logging on to the net. I just don't want to post my email address here.

If you switch the direct email facility on, I will send you a mail and you will then be able to contact me directly.

We'll get this script working!

No, I'm in the sunny UK!
