Question

I’m trying to use the sed command to replace text in a config file with the line

sed -e 's/pass/Awmusic12635/2w' -i config.yml

I have already cd to the directory to where the file is, but every time I run it I get the error

sed: couldn't open file : No such file or directory

What could be causing this?

OS: Ubuntu 10.10 32bit

Change your command to

$ sed -e 's/pass/Awmusic12635/2' -i config.yml

• it will change the second pass on every line to Awmusic12635
• if one line only contains single pass, it’ll not be replaced
• if you want to change every pass, just change 2(second) to g(global)
• w means write, but you didn’t provide a file name after w, so you see the err msg.
• -i option means edit-inplace, so you don’t need the w
