Can anyone help me please, I have a code which will retain number of files maximum of 3 and will remove the one on top (using head -1 command). See code below:
Code:
#!/usr/bin/sh
num_of_files=`ls /home/user/USER_LOGS/ | grep UserActivity | grep UMB00 | wc -l`
if [ $num_of_files -gt 3 ]
then
remove=`ls -lrt /home/user/USER_LOGS/ | grep UserActivity | grep UMB00 | head -1 | awk '{print $8}' | rm \`xargs\``
$remove
fi
The code is located on the same directory /home/nsadm/USER_LOGS/. It functions well trying to give the output that I want, however when I already went out of the sub-directory USER_LOGS hitting the command cd which by default will bring me to /home/nsadm/, then I tried to run the script as /home/nsadm/USER_LOGS/remover.sh, the script didn't work.
I hope anyone can suggest what to do because I'm planning to place this script in CRON. By the way, I've also tried to run the script as root user because only root user can deploy entries in CRON, so as per login default directory is /root (for root user), then I ran the script /home/nsadm/USER_LOGS/remover.sh, again it didn't work.
Here's the error that I've got:
Code:
rm: cannot remove `UMB00_UserActivity_20120103_094606.log': No such file or directory

SSS_USERADD(8) SSSD Manual pages SSS_USERADD(8)NAME
sss_useradd - create a new user
SYNOPSIS
sss_useradd [options] LOGIN
DESCRIPTION
sss_useradd creates a new user account using the values specified on the command line plus the default values from the system.
OPTIONS -u,--uid UID
Set the UID of the user to the value of UID. If not given, it is chosen automatically.
-c,--gecos COMMENT
Any text string describing the user. Often used as the field for the user's full name.
-h,--home HOME_DIR
The home directory of the user account. The default is to append the LOGIN name to /home and use that as the home directory. The base
that is prepended before LOGIN is tunable with "user_defaults/baseDirectory" setting in sssd.conf.
-s,--shell SHELL
The user's login shell. The default is currently /bin/bash. The default can be changed with "user_defaults/defaultShell" setting in
sssd.conf.
-G,--groups GROUPS
A list of existing groups this user is also a member of.
-m,--create-home
Create the user's home directory if it does not exist. The files and directories contained in the skeleton directory (which can be
defined with the -k option or in the config file) will be copied to the home directory.
-M,--no-create-home
Do not create the user's home directory. Overrides configuration settings.
-k,--skel SKELDIR
The skeleton directory, which contains files and directories to be copied in the user's home directory, when the home directory is
created by sss_useradd.
This option is only valid if the -m (or --create-home) option is specified, or creation of home directories is set to TRUE in the
configuration.
-Z,--selinux-user SELINUX_USER
The SELinux user for the user's login. If not specified, the system default will be used.
-h,--help
Display help message and exit.
THE LOCAL DOMAIN
In order to function correctly, a domain with "id_provider=local" must be created and the SSSD must be running.
The administrator might want to use the SSSD local users instead of traditional UNIX users in cases where the group nesting (see
sss_groupadd(8)) is needed. The local users are also useful for testing and development of the SSSD without having to deploy a full remote
server. The sss_user* and sss_group* tools use a local LDB storage to store users and groups.
SEE ALSO sss_groupadd(8), sss_groupdel(8), sss_groupshow(8), sss_groupmod(8), sss_userdel(8), sss_usermod(8).
