questions about some commands

[minus0]

Hi all,

I have a few questions

How do i open a large file using the VI editor? When i try to open a large file, get an error message saying "tmp file is too large to open" - I could temporarily solve my problem by FTP'ing the file to my hard drive and open it but is there any other way of doing this?

If i wish to kick off a job say on the last day and last hour of every month how do i check the date?

I set up aliases in my profile for CD'ing to a particular directory - for ex when i do $me i am taken to my home directory but how do i exectute this command (me) from within a shell script?

Also, is there some website that would give me some tricks/tips regarding VI editor?

I am a novice in UNIX which is the reason for all these questions

thanks for your time
Nask

how large is this file, the OS you are using ? the shell ?
i never, never got the error
"tmp file is too large to open"
my be your (/tmp or) /var/tmp is too small, /bin/vi
normally uses /var/tmp
in this case: add swap

Assuming you have permission to use cron then use
'crontab -e' to edit your cron file and add
00 23

whoops .. vi stuff covered by Iribach and Annihilannic

Assuming you have permission to use cron then use
'crontab -e' to edit your cron file and add
00 23 * * * <script> >logfile 2>&1

where <script> starts

#!/usr/bin/ksh
[ ! `date +%d` -eq `cal | tr '\012' ' ' | awk '{ print $NF }'` ] && exit 0
....
.... rest of code here
....

i.e run at 23:00 every day. Script compares today with the last day in the current month and exits if it isn't.
