Top Forums UNIX for Dummies Questions & Answers Schedule backup with crontab/tar Post 302851367 by Float on Sunday 8th of September 2013 11:24:42 AM

I just did this
Code:
Float@Float-Laptop /cygdrive/c/users/eirik
$ crontab -e
no crontab for Float - using an empty one
crontab: installing new crontab

Float@Float-Laptop /cygdrive/c/users/eirik
$ crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.nuaNGRIUgE installed on Sun Sep  8 17:11:48 2013)
# (Cron version V5.0 -- $Id: crontab.c,v 1.12 2004/01/23 18:56:42 vixie Exp $)
15 17 * * 7 tar cf important.tar important

and had no result. If this really is supposed to work, then I suspect that my terminal (Cygwin) might be bugged. Whenever I open crontab -e, I have to mash the keyboard for a bit before what I type comes visible, and if I try to paste code, then only the latter part of the code will be pasted. For example, when pasting
Code:
45 15 * * 6 tar cf Important.tar Important

What shows up is
Code:
mportant.tar Important

and there is a red alert in the bottom saying
Code:
E348: No string under cursor

Also, only occosionally when I push the Escape button I get to go on to type :wq to exit crontab -e. Usually when I press Esc, the code will just copy/paste itself some 20-30 times instead. There's also some other strange stuff going on, like when I use the arrow keys; sometimes it makes the "cursor" - the line that shows where I type - move, like it should, and other times it makes the letter A,B,C and D appear on the line above or below the code. This doesn't make much sense to me, but eventually I always get the code I want and I'm able to leave crontab, like now. As you can see, the code is as it should be. but maybe there's some invisible strange stuff going on here, messing up my crontab/tar scheme?

NAME
bcrontab - Manage users crontab files SYNOPSIS
bcrontab [ -u user ] file bcrontab [ -u user ] { -l | -r | -e } DESCRIPTION
bcrontab interfaces with the bcron-spool daemon to manage crontab files in the privileged spool directory. OPTIONS
-u user Tell bcron-spool that we are acting on behalf of the named user. bcron-spool will only accept the username if bcrontab is running as either root or the same user ID as the named user. -l List the cronab crontab to standard output. -r Remove the user's crontab. -e Edit the current crontab. ENVIRONMENT
VISUAL If this is set, it is used as the editor to invoke to edit a crontab. EDITOR If $VISUAL is not set and this is, it is used as the editor to invoke to edit a crontab. If neither are set, /bin/vi is used. BCRON_SOCKET The path to the named socket used to communicate with bcron-spool. Defaults to /var/run/bcron-spool. LOGNAME USER These two variables are used, in order, to determine the user name invoking the program. One must be set if the -u option is not used. FILES
bcrontab tries to writes a temporary file into the current directory, and then into /tmp if that fails, in order to edit the current crontab. SEE ALSO
