pc (print column) CLI utility

A simple utility to print the desired column from tabular data, to replace verbose awk invocations:

ls -l | awk '{ print $2 }' becomes ls -l | pc 2

Inputs

pc can read from stdin:

$ ls -l | pc 2

# OR

$ pc 1 < ls -l

as well as a given filepath:

$ pc 1 ~/data.txt

Delimiter

You can specify the delimiter pc uses to split lines into columns, with the default being space. Any consecutive delimiter characters will be considered a single column delimiter:

"test1 test2" will be split the same as "test1 test2"

You can provide alternate delimiters with the --delimiter option:

$ echo "1,2,3,4" | pc 2 --delimiter ,
2

Output Separator

The default output separator is a newline:

$ echo "1 2 3 4\na b c d" | pc 2
2
b

but you can provide a different character to print between each matching column:

$ echo "1 2 3 4\na b c d" | pc 2 --separator "|"
2|b|%
