I'm trying to find and replace the contents of a file using grep and sed.

grep "#!/bin/bash" ./ | sed xargs -i 's/#!/bin/bash/#!/usr/bin/env bash'

How do I make sure that the string #!/bin/bash will parse as string and not confused the demiliter /?

  • Use ´\´ to escape '/' in your search/replacement strings.

  • As a sidenote, I assume you meant /usr/bin/env?

You can either escape the / with \ or use a different delimiter for sed.

Sed can also use delimiters like _ or %
