Help on script to change permissions
Hi

I have written the following script that later I want to put in cron,:

Code:
#!/bin/bash
_find="/usr/bin/find"
_paths="/moneta_polled01/mediation_gsm /moneta_polled01/mediation_mmsc"
for d in $_paths
do
$_find $d -type f -exec chmod 777 {} \;
done

but it does not seem to be working for the second subdirectory define on line 3.

Please can you help

Hello,

put set -x on the second line, and run script again to see the problem.

still not working, this is what is doing:

Code:
root@moneta # ./perm
+ _find=/usr/bin/find
+ _paths='/moneta_polled01/mediation_gsm /moneta_polled01/mediation_mmsc'
+ for d in '$_paths'
+ /usr/bin/find /moneta_polled01/mediation_gsm -type f -exec chmod 777 '{}' ';'

There is no reason it not executing unless and that you say nothing, you are not executing the script as root.. in which case it cannot change what doesnt belong to the UID running the script...

I think, find would be executed in its own shell (subshell) and you dont need to escape ";"at all.

try

Code:
 $_find $d -type f -exec chmod 777 {} ;

Hi

It looks like its working, what I think is happening, is because these directories are being feed with files all the time, it looks like is not working, but it is.
But I dont quite understand why a cron entry with chmod command doest not work:

Code:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /usr/bin/chmod 777 * /moneta_polled01/mediation_gsm

---------- Post updated at 03:10 PM ---------- Previous update was at 03:02 PM ----------

after removing "\" as suggested by vidyadhar85, I got the following:

Code:
 ./perm
+ _find=/usr/bin/find
+ _paths='/moneta_polled01/mediation_gsm /moneta_polled01/mediation_mmsc'
+ for d in '$_paths'
+ /usr/bin/find /moneta_polled01/mediation_gsm -type f -exec chmod 777 '{}'
/usr/bin/find: incomplete statement
+ for d in '$_paths'
+ /usr/bin/find /moneta_polled01/mediation_mmsc -type f -exec chmod 777 '{}'
/usr/bin/find: incomplete statement

cron:
Should be
Code:
/usr/bin/chmod 777  /moneta_polled01/mediation_gsm/*

You need \ it is part of find syntax...
