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
