I have something like below, the result of the grep is assigned to abcd variable

abcd=`grep -n "^AB.*123456.*" /tmp/file | cut -d: -f1`

when I try to echo this result to a file using echo $abcd>> /tmp/abc it is not working
It works when I run from the command prompt and this gets assigned to abcd but when I try to print the value using echo $abcd i dont get any results..

It seems to work for me. What shell are you using? Bash, Bourne shell, Korn shell? Does the file /tmp/abc exist already before you run the echo command? Is NOCLOBBER set?

Can you echo anything into the file? For example: echo text >> /tmp/abc Does that work?
 
I agree. Here's the link: http://aspose.com/file-tools
