    sed 's/regular_expression/replace/' filename
  • Replace all occurrences of an extended regular expression in a file, and print the result:
    sed -r 's/regular_expression/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
  • Delete lines matching the line pattern:
    sed '/line_pattern/d' filename
  • Print the first 11 lines of a file:
