How to insert text after a block of text?
Input:
Code:
fstab is a configuration 
file that contains information 
of all the partitions 

and storage devices 
in your computer. 

The file is located under /etc, 
so the full path 
to this file is /etc/fstab.

The >>>>> characters would be replaced by some texts.
For example if i run a shell script,
Code:
./run.sh sometexts infile

Output would be:
Code:
fstab is a configuration 
file that contains information 
of all the partitions 
sometexts

and storage devices 
in your computer.

The file is located under /etc, 
so the full path 
to this file is /etc/fstab.

Using sed to replace the >> character

Code:
#!/bin/ksh
#save file as run.ksh

sed "s/>>*/$1/g" $2 > outfile
