Split rows
Hi all,
I need a simple bin/sh script

FILE1:
Code:
ab1  gegege swgdeyedg
ac2 jxjjxjxjxxjxjx
ad3 
ae4 xjxjxj zhzhzh ahahs
af5 sjsjsjs ssjsjsjsj sjsjsj
ag6 shshshshs sjjssj
shhshshs

myScript.sh has to return:
Code:
ROW ab1
ROW ac2
ROW ad3
ROW ae4

In other words: "ROW " + the first world of the first 4 lines

Thanks
RIccardo

If you need only a solution for your problem:
Code:
awk 'NR<5{print "ROW" FS $1}' file

If this is a homework and you are limited to sh please post your problem on Homework & Coursework Questions - The UNIX and Linux Forums

Code:
#!/usr/bin/bash
for file in `cat "file.txt" | grep -v "shhshshs" | awk '{print $1}'`
do
echo ROW $file
done

Code:
leo@lein:~/Escritorio$ cat file.txt
ab1  gegege swgdeyedg
ac2 jxjjxjxjxxjxjx
ad3 
ae4 xjxjxj zhzhzh ahahs
af5 sjsjsjs ssjsjsjsj sjsjsj
ag6 shshshshs sjjssj
shhshshs
leo@lein:~/Escritorio$ bash shell.sh
ROW ab1
ROW ac2
ROW ad3
ROW ae4
ROW af5
ROW ag6
leo@lein:~/Escritorio$
