I have a file I want to modify every line in this file except the frist line in the file?
sed s/$/whatever
how would I skip the fisrt line and do this command on the rest of the file?

Try this

sed 2~1s/pattern1/pattern2/ file.txt

The 2 means start at line 2. The ~ means step by the next value.

ok headrush one more question

Since I am using control M as a character I cannot type that. So I have a file with this in it

s/run "ds03853^M1^M//

I want to remove the run part of a 390 line file. I only need the unr onme the first line. When I added the 2~1 in front it failed to run. any clues how to do it int he script file?

What is the exact syntax you are using? (command in a script or inline to sed)

[surfnschultz]

so I am doing this

at the prompt I am type sed -f invloc data > dataout

invloc looks like:
s/run "ds03853^M1^M//

data looks like

run ds03853^M1^M982109^M982109^M3^MY^M

there are 390 lines ilke this in data and I want the first line to stay untouched. and the rest to eliminate the run part.

[surfnschultz]

I can manipulte the data with vi, but would prefer to do it once with a script

[Headrush]

I'm a little confused.
Would you please post a paragraph or so of your input file and bold the part you want to search for and remove.

I know after the 1 line, but confused about the length and content after the run.

Seems like it would be easier to just remove them all and then run another sed statement to put the run back into the first line. I am pretty sure you can have sed stop after the first match so it would just put the run back on the first line. In fact I am pretty sure you can tell sed what line you want to edit so you could just specify line 1 in the sed script.
