Use Python to make the first field of a text file uppercase:

#!/usr/bin/python3
import sys,re
for line in sys.stdin:
    word=line.split()
    word1=re.split("\s",line)[0]
    word1=word1.upper()
    print(str(word1)," ".join(word[1:]),end=" ")
    print()

Column

Format a .CSV file in columns like a spreadsheet:

column asteroids.csv -t -s ","

#! /bin/bash
printf "hex2dec=";echo "ibase=16;$1"|bc
printf "dec2hex=";echo "obase=16;$1"|bc
printf "oct2dec=";echo "ibase=8;$1"|bc
printf "dec2oct=";echo "obase=8;$1"|bc
