If awk is allowed:

Code:
awk -v s=$string '!/T00:00:00$/{$(NF+1)=s}1' file > newfile

Thanks Franklin

Nearly there, but $string is being written one-space into the beginning of the line, not at the end.

Trying to work it out but haven't cracked it yet!

It works fine for me, can you post some lines of your file including a line without the specific string at the end?

Nearly there:

awk -F"|" -v s=$string '!/T00:00:00/{$NF=s}1' file > newfile

(Forgot to mention that each line in the file has | as the field delimiter).

This line is writing $string to the end of the line, but replacing all my | delimiters with spaces! Smilie

Any ideas why it is doing this?

much appreciated

Try this:

Code:
awk -v s=$string 'BEGIN{FS=OFS="|"}!/T00:00:00$/{$(NF+1)=s}1' file > newfile

With $(NF+1)=s I add a new field at the end of the line but with $NF=s you're replacing the last field with your string.

That's done it!

Code:
 
awk -v s=$string 'BEGIN{FS=OFS="|"}!/T00:00:00/{$NF=s}1'

Perfect, thank you Franklin! Smilie

(It seems to work fine replacing the last field, I believe the field is there but just empty).
