rm error codes and logging
Afternoon ladies and gents,

I am trying to create a simple script to remove a certain file from a user's network profile location. The removal works ok, but in the interest of overkill I would like to add a simple error detection (such as file doesn't exist or permission denied)

Currently, it works perfect assuming nothing is missing and I have permissions to run it. It outputs all the removed files to the log. If permission denied or file does not exist, it skips the append ending and dumps it into terminal. Is there any way I may be able to log the errors as well?

Part in question:
Code:
array=( $( ls -1p | grep / | sed 's/^\(.*\)/\1/') )
for (( i=0; i<${#array[*]}; i++));
    do
        rm -v /profiles/${array[i]}path/to/file.extension >> ~/Desktop/MyLog.log
    done

Note: The $array variable returns "FolderName/" instead of just "FolderName". This explains it being "/profiles/${array[i]}path/to/file.extension" instead of "/profiles/${array[i]}/path/to/file.extension".

I understand it may involve a small "if-then" statement, I am just clueless go about it.

Thank You!

Dave_L on Ubuntu Forums solved this (very quickly I might add).

Code:
rm -v /profiles/${array[i]}path/to/file.extension >> ~/Desktop/MyLog.log 2>&1

Adding "2>&1" after MyLog.log was the fix.

Thanks!

aa-genprof

GENPROF(8)							     AppArmor								GENPROF(8)

NAME

       aa-genprof - profile generation utility for AppArmor

SYNOPSIS

       aa-genprof <executable> [-d /path/to/profiles]

OPTIONS

       -d --dir /path/to/profiles

	  Specifies where to look for the AppArmor security profile set.
	  Defaults to /etc/apparmor.d.

DESCRIPTION

       When running aa-genprof, you must specify a program to profile.	If the specified program is not a fully-qualified path, aa-genprof will
       search $PATH in order to find the program.

       If a profile does not exist for the program, aa-genprof will create one using aa-autodep(1).

       Genprof will then:

	  - set the profile to complain mode

	  - write a mark to the system log

	  - instruct the user to start the application to
	    be profiled in another window and exercise its functionality

       It then presents the user with two options, (S)can system log for entries to add to profile and (F)inish.

       If the user selects (S)can or hits return, aa-genprof will parse the complain mode logs and iterate through generated violations using
       logprof(1).

       After the user finishes selecting profile entries based on violations that were detected during the program execution, aa-genprof will
       reload the updated profiles in complain mode and again prompt the user for (S)can and (D)one. This cycle can then be repeated as neccesary
       until all application functionality has been exercised without generating access violations.

       When the user eventually hits (F)inish, aa-genprof will set the main profile, and any other profiles that were generated, into enforce mode
       and exit.

BUGS

       None. Please report any you find to bugzilla at <http://bugzilla.novell.com>.
