sed

Run replacements based on regular expressions.

  • Replace the first occurrence of a string in a file, and print the result:

sed 's/{{find}}/{{replace}}/' {{filename}}

  • Replace all occurrences of an extended regular expression in a file:

sed -E 's/{{regex}}/{{replace}}/g' {{filename}}

  • Replace all occurrences of a string in a file, overwriting the file (i.e. in-place):

sed -i '' 's/{{find}}/{{replace}}/g' {{filename}}

  • Replace only on lines matching the line pattern:

sed '/{{line_pattern}}/s/{{find}}/{{replace}}/' {{filename}}

  • Apply multiple find-replace expressions to a file:

sed -e 's/{{find}}/{{replace}}/' -e 's/{{find}}/{{replace}}/' {{filename}}

  • Replace separator / by any other character not used in the find or replace patterns, e.g., #:

sed 's#{{find}}#{{replace}}#' {{filename}}
