I wrote a script like
#!/bin/bash echo $1 > temp cat $2 >> temp mv temp $2 now I have problem appending the above script(only using bash shell) so that it now inserts the first argument into the middle of the file. I have tried using $(('wc -l < file' / 2 )) but invain so could any one help. Reply With Quote Last edited by boris; 04-13-2007 at 11:43 AM.

something like this,
to be in the middle Code:
a=$((`wc -l < filename` / 2))
awk -v var=$a '{ if( NR == var) { print "newline to be added"; print } else { print } }' filename > newf
mv newf filename
