Shell Programming and Scripting

I have a script that runs every hour from the crontab (see the settings of the crontab below) (15 mins past the hour)

Code:

15 * * * * /home/usr/usr1/ProvAll

This script saves two files in the following format

Code:

now=`/bin/date '+%Y%m%d.%H%M%S'`

file1.$now (for example)
file1.20140722.031502
file2.20140722.031502

I would need help in writing another script and kick of using the following crontab settings (20 mins past the hour)

Code:

20 * * * * /home/usr/usr1/mynewscript

the purpose of this "mynewscript" is to

1) to check if there are any files with the above format written in the directory in the last 10 mins

file1.20140722.031502
file2.20140722.031502

2) if the files are there then check the size of those files, if the file size of the files are zero then exit else

3) grep for a word 'xyz' from those file and save the output into a new file (xyzfound) if that word is found

If the directory is /path/to/search

Code:

 
for i in $(find /path/to/search -type f -mmin -10)
do
  if [[ -s "${i}" ]]; then
    grep "xyz" "${i}" >> xyzfound
  fi
done

find: bad option -mmin
find: [-H | -L] path-list predicate-list

What's your OS?

Sun Solaris 10

Why don't you perform the checks in your first script? It should know if it has written the files, size can be immediately checked, as well as the xyz contents...

Hello knijjar,
I have a few to questions pose in response first:-There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.

It seems like you might need a trick to work out the time 10 minutes ago, create a reference file with the correct time stamp and then use the -newer flag of find.
