UNIX for Dummies Questions & Answers

Hello All,

I am trying to put this line in Crontab (Linux box- x86_64), but the command is not running. Can you please help me out? My requirement is-

To find out the number of .csv files older than 1 day in directory /stage/landing. There are 2 other subdirectories under this directory also.

50 4 * * * test -d /stage/landing && find /stage/landing -mtime +1 -type f -exec 'ls -l *.csv | wc -l' "{}" \; >/dev/null 2>&1

Thanks,
Naresh

Code:

find /stage/landing -mtime +1 -type f -name "*.csv" -exec wc -l {} \;

It think that ROHON's version will count the number of lines in each file.

This will count the number of files. Bear in mind that the output will be in unix mail for the owner of the cron. You have no code to put the answer anywhere useful.

Code:

50 4 * * * [ -d /stage/landing ] && find /stage/landing -name '*.csv' -type f -mtime +1 -print | wc -l

Oh yes..!! I did a mistake in placing the wc -l. Thanks methyl for correcting me.

Thanks buddies for your replies. By the way I tried like this, isn't it correct? I greped it (| wc -l).

20 11 * * * find /stage/landing -mtime +1 -type f -name "*.csv" | wc -l > /home/naresh/older1day.out 2>&1

this is same as what methyl has suggested.

If in your original version you are trying to send error messages from "find" to /dev/null , I'd change the line slightly to prevent error messages appearing in your output file. I guess that your version of "find" does not need "-print" (some versions do, some versions don't).

Code:

find /stage/landing -mtime +1 -type f -name "*.csv" 2>/dev/null | wc -l > /home/naresh/older1day.out
