# print line number 52
sed -n '52p' # method 1
sed '52!d' # method 2
sed '52q;d' # method 3, efficient on large files

That works wonderfully thankyou. However do you know how I can allow the shell to recognize the variable in this:

sed '$Variableq;d' files

Thanks

Bash script:

Code:

#!/bin/bash
VARIABLE=2
cat example.txt | sed $VARIABLE'q;d'

Command line:

Code:

VARIABLE=2; cat example.txt | sed $VARIABLE'q;d'
