## Comparison to sed ## Comparison to sed
Although `sed` has a nice regex syntax with `-r`, it is not portable and doesn't work on, say, MacOS or Solaris. Also, `sed` is far more powerful. Focusing on just finding and replacing allows `sd` to make this common task far more straightforward.
Some cherry-picked examples, where `sd` shines: Some cherry-picked examples, where `sd` shines:
- Replace newlines with commas: - Replace newlines with commas:
- `sed ':a;N;$!ba;s/\r/,/g'` vs - sed: `sed ':a;N;$!ba;s/\r/,/g'` vs
- `sd -r '\r' ','` - sd: `sd -r '\r' ','`
- Extracting stuff out of strings with special characters
- sd: `echo "{((sample with /path/))}" | sd -r '\{\(\(.*(/.*/)\)\)\}' '$1'`
- sed
- incorrect, but closest I could get after 15 minutes of struggle
