you need to put the line :
0,5,10,15,20,25,30,35,40,45,50,55 7,8,9,10,11,12,13,14,15,16,17,18,19 * * 1,2,3,4,5 /command
into your crontab file.

By edit your crontab:
crontab -e
(Warning: vi-mode, you can leave without changes by ESC :q!)

# Minute0-59 Hour0-23 Day1-31 Mont1-12 Weekday0-7 Command
/5 7-19 * * 1-5 ls >> /tmp/ls.txt


This will run every 5 Minutes an "ls" and append the output at the end of /tmp/ls.txt , but not all can understand "/5", then use "5,10,15,..."
Check is the owner of the crontab (=the user you edited with) has the permissions to do that.

My script dosent work when i run it as a cron job.
this works when run from the shell.

what might be the reason it is soo.

the script jus redirects a commands output to a file .it the serches the file for a pattern usin grep and execute some commands if the pattern is found.



cd /take/to/the/directory
. ./test.1>test_out
. ./test.2>>test_out
grep -q "somethin" test_out
s1=$?
if [ $s1 -eq 0 ]
then
echo
#echo "test.1---------successful"
else
mailx -s "obj Down" x@w.com<test_out
fi

grep -q "somethin_agen" test_out
s2=$?
if [ $s2 -eq 0 ]
then
echo
#echo "test.2---------successful"
else
mailx -s "obj 2 don" x@w.com<test_out
fi

*test.1 and test.2 are properly working scripts

How do you call it in the crontab ( /take/to/the/directory/test.1> test_out ) ?

It's better to use crontab just to call other scripts, without any parameters (it may work, but not on all plattforms).
You can direct the output of a script in itself by "exec >> /var/xyz.log".

I would say it's because you aren't using complete path names. Also check the test.1 and test.2 and make sure they have full pathnames.
I would change the scripts to something like this:

###########################################
/take/to/the/directory/test.1 > /take/to/the/directory/test_out
/take/to/the/directory/test.2 >> /take/to/the/directory/test_out
grep -q "somethin" /take/to/the/directory/test_out
s1=$?
if [ $s1 -eq 0 ]
then
echo
#echo "test.1---------successful"
else
mailx -s "obj Down" x@w.com< /take/to/the/directory/test_out
fi

grep -q "somethin_agen" /take/to/the/directory/test_out
s2=$?
if [ $s2 -eq 0 ]
then
echo
#echo "test.2---------successful"
else
mailx -s "obj 2 don" x@w.com< /take/to/the/directory/test_out
fi
###########################################
