A field selection command-line tool

Project description

# sel

sel is an inline field selection and table transformation tool that aims to replace cut.

pip install sel

## Simple

Selecting a field from a line requires a single character:

$ echo a b c d e | sel 3 c

sel understands field ranges, in python style:

$ echo “a b c d e” | sel 2:4 b c d

$ echo “a b c d e” | sel 2:-2 b c d

$ echo “a b c d e” | sel 3: c d e

## Flexible

By default, sel splits the input on whitespace. It can also use a custom string or regular expression:

$ cat users.csv 1241,Bob 3192,MitM 3255,Alice

$ cat users.csv | sel 1 –delim , 1241 3192 3255

$ echo 1a2b3c4d | sel –regex [a-z] 2:3 2 3

## Powerful

sel works well on multiline input, and can take advantage of table headers if present. It can also produce tabular outputs.

$ ps aux | sel 1 –skip-header root user1 user2

$ ps aux | sel –align %MEM PID COMMAND PID COMMAND %MEM 2414 /opt/google/chrome/chrome 1.7 5272 /opt/sublime_text_2/sublime_text 1.6 4662 /usr/bin/python3 1.5 2470 /opt/google/chrome/chrome 1.5
