sed add line under a specific line in a file

aristosv · 08-30-2015, 01:40 AM

I am trying to add a line under a specific line in a file.

This is the command I am using.

Code:

/bin/sed -i -e 'export s_sshhost="host.name.here1"/a export s_vpnhost="host.name.here2"' /root/testfile

This is the output

Code:

sh: 1: xport: not found

Is there something wrong with my syntax?

Thanks

Yes, there is. Your slash before the 'a' is supposed to be the other way. Like this:

Code:

$ cat sedapp.txt 
A line
Another line
...and the final line

Code:

$ sed '/A line/ a\New line' sedapp.txt 
A line
New line
Another line
...and the final line

Best regards,

no that didn't do it. I get the exact same message.

this doesn't produce an error, but it doesn't modify the file either

Code:

/bin/sed -i -e '/export s_sshhost="host.name.here1"/ a\export s_vpnhost="host.name.here2"' /root/testfile
