Find Command

Kavita Poonia — Mon, 17 Nov 2008 21:12:15 GMT

Hello all,

I want to find out the files under a directory which are modified from past 2 days. Then what syntax should I use with find command.

Is the below format okay .........

find /opt -xdev -mtime 2 -exec ll {} \;

Thanks * regards,
Kavita

If you want all files modified during the last 2 days, then you need to use a '-2'.

find /opt -xdev -mtime -2 -exec ll {} \;

Hi:

Use this:

# find /opt/ -xdev -type f -mtime -2 -exec ls -l {} +

This limits your search to *files* that have been modified sometime in the last 2-days (where a day is exactly 24-hours). The '-exec' argument is terminated with a "+" instead of a ";". This causes multiple arguments to be passed to your 'ls' greatly reducing the number of forked processes and thereby greatly improving overall performance.

Regards!

Thanks Patrick and James.........It was really very helpful.......so if I want to see any file which is modified in past x days then I have to specify -x with -mtime......one more thing how can I find a file under a directory which is growing continuously with find command........

Yes. But it is exact. It will not return files modified exactly 2 days ago or 2.5.
Caution, if you export UNIX95, the dates are completely different.

>how can I find a file under a directory which is growing continuously with find command

This requires you to create a "database" with the size the last time you checked.
Of course, if the file is always being appended, then all you need is that it was modified.
