How to display the current month using cal

nisagnel · 10-15-2014, 03:11 AM

Hi evo2,

can it be used like the following?

cal | head -n1 | awk '{print $1}' | tr '[:lower:]' '[:upper:]'

I am not sure why we cannot use [a-z] and [A-Z].I have checked the man page of tr.it suggests to use '[:lower:]' '[:upper:]'.

Well, I was trying to get the OP to read the man pages... but it looks like you did. Why are you messing with head and awk though? Only cal and tr should be used/needed.

ok.got it.

I thought hello111 needs only the name of the month in upper case.that's why i used awk and head.

you do not need head if you have awk (my god):

Code:

cal | awk '{ print toupper($1); exit }'

Ahh, ok. It seems we had different interpretations of:

Quote:

Display the current month using 'cal', translating to uppercase using 'tr'.

You're thinking the name of the month while I'm thinking the calendar for the month. My interpretation was mainly based on the limited tool set (cal and tr) that the question mentioned.
