Hi!

I have a linux-box, where I only have ftp-access and procmail!

I want to install a cron-job.
The only way how I can run jobs with my user-id is IMHO procmail!

for this I would need a solution how to make something like:

vi < input.txt

input.txt:
---
iTEST^[:wOUT1
:q                                                                                                            

---

this doesn't work because vi wants a terminal - any ideas??

thanks
witty

but I don't want to write to a file, but to "crontab"!
"crontab -e" opens an editor!

echo TEST | crontab -e
or
cat file | crontab -e
or
crontab -e < file

don't work:
Vim: Warning: Input is not from a terminal

Hey there,

if you want to edit your crontab via command line, you must use redirection, and filters.
example to add a line:
cp /var/spool/cron/crontabs/<user> temp-cron
echo "Crontab entry" >> temp_cron
crontab temp_cron

example to delete a line containing a command called "wakeup":
cp /var/spool/cron/crontabs/<user> temp-cron
grep -v wakeup temp-cron > temp-cron
crontab temp_cron

example to substitute a command called "one" with another command called "two":
cp /var/spool/cron/crontabs/<user> temp-cron
sed s/one/two/g temp-cron > temp-cron
crontab temp_cron

Remember that <user> stands for the user you're using.

hope this helps...-garisoain
