Tools How to eliminate extra char?
I was trying to grep a variable with one space in my file:
questionlabel=Q1

more job.tex
Q1 pear
Q1A applie



grep -i "$questionlabel\ " job.tex > tmp


But I keep getting :
Q1 and Q1A both in my tmp


Thanks!!!!

Since Q1 is in the second line, you WOULD get that also.

Change your variable to "Q1 " - then you will only get the pear line (note you have to quote it when setting the variable).

Question variable
In reality I won't know the value of my variable.

grep -i "$questionlabel\ " job.tex > tmp

Should replace the variable with a valure passed to it and add a space at the end.


Does anyone know how to do it?

I am so sorry for the trouble I made.
I had problem with my other part of code.
It turned out that this code was never runned!


Thank you for your help, RTM.

Your answer made me doubt my other code.

I've tried this on HP-UX and Linux the results are as expected. I.e.

input file contains...
Q1 pear
Q1A apple

Then at the prompt....
Code:
$ var="Q1"  # without a space
$ grep "$var\ " somefile
Q1 Pear

If this isn't working for you, try grep "$var[ ]" somefile

Cheers
