Hi,

Can someone tell me how to append some text to the last line. Basically i have a last line of a file as follows

user1:password

i would like to append ':systemuser' to the last line of this file as follows

user1:password:systemuser

I have tried doing this with cat but cat adds a new line in the end which i do not want !

Thanks in advance

Shell commands can append to a file, but that would be AFTER that last newline character. You are wanting to modify the last line, so you need to output a new file, such as:

sed '$s/$/:systemuser/' infile > outfile

James,
Thanks for the help !! ..

i had also tried sed but was missing the '$' sign to concat at the end of line

How can i append a new line charater at the end of file.

Thanks
Sri

echo >> myfile

If the last line of myfile was properly terminated with a newline character, the above will add an additional empty line.

If the last line of myfile was "incomplete" (not terminated by a newline character), the above will add the newline character to it, thus completing that line.
