Unix Tip #4555- August 31, 2023
SEARCH AND EDIT IN ONE
Want to search all files for in the local directory for
a string and then edit them in vi?
This will do it.
vi `grep -il "target" *.sql 2>/dev/null`
Search all files in a directory structure for
a regular expression and edit with vi.
vi `find . -type f -name "*.sql" -print | (xargs grep -il "[a-z][a-z]*get" 2>/dev/null)`
It's a good idea to redirect stderr in case you come
across files for which you don't have read permissions.
The errors messages would be passed as arguments to
vi.
