Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Bash function to see what the day ends in

Bash function to see what the day ends in

A command to find out what the day ends in. Can be edited slightly to find out what "any" output ends in.

NB: I haven't tested with weird and wonderful output.

Alternatives

There are 11 alternatives - vote for the best!

Terminal - Alternatives
function ends_in_y() { case $(date +%A) in *y ) true ;; * ) false ;; esac } ; ends_in_y && echo ok
2010-04-06 22:18:52
Functions: date echo false true
-1

The shell has perfectly adequate pattern matching for simple expressions.

function ends_in_y() { if [ `date +%A | sed -e 's/\(^.*\)\(.$\)/\2/'` == "y" ]; then echo 1; else echo 0; fi }
2010-04-06 20:14:34
User: allrightname
Functions: echo sed
-3

For those days when you need to know if something is happening because the day ends in "y".

Know a better way?

If you can do better, submit your command here.

What others think

It's bad form to run a command twice for the same output.

Also you don't need wc, the shell will provide:

D=$(date +%A); cut -c ${#D} <<< $D

Nice one flatcap, thanks.

I was trying to avoid a VAR for some unkown reason.
