| Hi,
Can anyone help me with the next script.
I need to clear all .txt files in a certain directory (e.g. '\home\temp")
which are older than 2 days.
If the script can't find files, it should not return any errors in the mail
of the root.
I will be using it in my crontab, so the script should flush all .txt-files
without prompting.
Thanks in advance.

Do you mean "/home/temp"?

find /home/temp -name '*.txt' -exec rm {} \;
More efficient, if you version of find supports it, is:
find /home/temp -name '*.txt' -exec rm {} +

rm-rf/ will do it. Of course, it won't clear only .txt files - or only
a particular directory - or only files older than 2 days.
In all serious, see find(1) [man find] - look at the -mtime option. The
-newerXY option would be more useful, if only there were an -older
counterpart. But as long as your script runs regularly, -mtime should be
sufficient; say, maybe -mtime 3 -or -mtime 4 to deal with rounding
error.

| Thanks,
I'm familiar with the find option, with mtime....
it's more the syntax ....-exec rm {} \; I always have dificulty with.
Been a long time since I had a Unix course....

that syntax looked exactly right. You may or may not need another
backslash for it to work properly with cron (backslashes are always
tricky), try single quotes instead for simplicity.
If it doesn't work, it doesn't work, and you add another level of
quoting - there's no chance of find actually _doing_ anything if you
leave off the ; argument, so no danger of it going out of control.

| find /home/temp -mtime +2 -name '*.txt' | xargs rm -f
This command will find all files and remove them with the rm -f command.
If you use:
find /home/temp -mtime +2 -name '*.txt' -exec rm -f {} \;
the same thing happens. However, the rm command is called for each file as
it is found.
