> 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 only on lines matching the line pattern:
|
||||
|
||||
`sed '/{{line_pattern}}/s/{{find}}/{{replace}}/'`
|
||||
|
||||
- Replace all occurrences of a string in a file, overwriting the file (i.e. in-place):
|
||||
|
||||
`sed -i '' 's/{{find}}/{{replace}}/g' {{filename}}`
|
||||
|
||||
- Replace all occurrences of an extended regular expression in a file:
|
||||
|
||||
`sed -E 's/{{regex}}/{{replace}}/g' {{filename}}`
|
||||
|
||||
- Apply multiple find-replace expressions to a file:
|
||||
|
||||
`sed -e 's/{{find}}/{{replace}}/' -e 's/{{find}}/{{replace}}/' {{filename}}`
