Re: Reading a particular line in a file

Thats a great one!

I'm always amazed what can be done using head, tail, grep , sed and awk.

I tried your example and couldnt get it to work, how do you specify INDEX?
I tried
sed -n "${22}p" filename (listed whole file)
sed -n "${cat testfile}p" filename (bad substitution)
sed -n "${22,23,24}p" filename (bad substitution)
sed -n "${22 23 24}p" filename (bad substitution)

This works:
sed -n "22p" filename
