How to indent grep's output? I need grep's output to be indented with tabs/spaces. This is the plain, un-indented version: `MyCmd | grep "id:"` I tried this without success:`MyCmd | grep "id:" | echo " "`

You could do it with `awk` instead of `grep` if that's acceptable:


MyCmd | awk '/id:/ {print " " $0}'


or if you need grep, `sed` could help:


MyCmd | grep "id:" | sed -e 's/^/ /'


The `awk` version does its own pattern match for lines that contain "id:" and then will print the spaces before the line. The `sed` version does the `grep` as you already did it but then replaces the start of each line (regex `^` matches the start of a line) with the spaces
