CLI

Intro

This is the list of CLI tools I found useful someday. It is useful reference as remembering all script names and options is cumbersome. Especially those I use rarely.

ripgrep

rg (ripgrep): great grep replacement.

Recursive search and respects .gitignore by default.

Possible to configure per repository with .rgignore

Useful options:

• -i: case insentive
• -v: invert matching
• -A n(after), -B n(before), -C n(context). n is number of lines
• -u, -uu, -uuu: unrestricted searching with gitignored, hidden, and binary files
• -l: list files matching
• -e: pattern (regex) to search for. Useful when using multiple patterns
• -o: show only matching fragment

jq

jq: JSON command-line processor

Very powerful but it’s difficult to get used to the syntax.

Basics:

• . (dot) is root
• .[index]: access array index
• .key: access key in object
• .[]: array/object iterator
