Hi,
I am trying to copy one field to another only on lines that match a certain string. Here is what i have tried:
awk '/nch/' {gsub($3,$5,$0)}' file
I need to copy $5 (field) to $3 if the line contains "nch"
I have never used gsub and am not sure if this is the right way.
file:
----------------------------------------
mod pad1 pad2 pad3 pad4 col row etc
nch pad4 pad5 pad6 pad7 col1 row1 time
nch pad2 pad3 pad5 pad8 col row date
----------------------------------------
Thanks for any suggestions.
