rd

Very simple utility to replace(r)/delete(d) strings in text files

installation

bash cargo install rd

usage

bash rd "replace" "with" -f file.txt by default, it uses regex, for string literals

bash rd -s "replace" "with" -f file.txt

replace inplace by

bash rd "replace" "with" -f file.txt -i

delete matching lines

bash rd "to_delete" -f file.txt -d

modify multiple files

bash rd "replace" "with" -f *.txt with fd bash rd "replace" "with" -f $(fd '.*\.txt')

performance

Much faster than GNU sed (2x), but slower than sd (2x) for large files. Similar to sd for small files

Good Design Choices

1. Do not touch the file unless there is a change. This is useful when modifying a long list of files and do not want to leave a trail in every files pass on the command line
