Shell Script to zip users cmd history log files

Shell Programming and Scripting
1

I admit I am terrible with scripting, so when I was asked to store users' command history lines and zip them on monthly basis what I did was to create a file "user_history_Feb" with the following contents:

Part A

[root@H99XXX bin]# more user_history_Feb
cp -p /var/log/user_history/*history /var/log/user_history/old_logs/
gzip -9 /var/log/user_history/old_logs/*history
cd /var/log/user_history/old_logs
mv *gz /var/log/user_history/old_logs/02
[root@H99XXX bin]#

and a cronjob for it to run end of Feb:

Part B

[root@H99 bin]# crontab -l | grep user_history_Feb
01 22 29 2 * /usr/local/bin/user_history_Feb
[root@H99 bin]# uname -a
Linux H99 2.6.18-274.17.1.el5 #1 SMP Wed Jan 4 22:45:44 EST 2012 x86_64 x86_64 x86_64 GNU/Linux
[root@H99 bin]#

I am using RHEL 5.7

I know my "script" is no script, and would be very thankful if someone could help me into scriptifying part A so I can adjust the cron :o

PART A:

Script user_whtever.sh

#!/bin/bash
 
mkdir -p /var/log/user_history/old_logs # If the folder is not present, it will be created automatically
 
cp -p /var/log/user_history/*history /var/log/user_history/old_logs/
gzip -9 /var/log/user_history/old_logs/*history
mv /var/log/user_history/old_logs/*.gz  /var/log/user_history/old_logs/02

After you have created the above script, change its permission:

 
[root@H99XXX bin]# chmod 750 user_whtever.sh
 
[root@H99 bin]# crontab -l | grep user_
01 22 29 2 * /usr/local/bin/user_whtever.sh

[PS: /var/log/user_history/old_logs/02 is file or folder?]

It's a directory

[root@H99 ~]# ls -ld /var/log/user_history/old_logs/02
drwxr-xr-x 2 root root 4096 Feb  1 14:52 /var/log/user_history/old_logs/02
[root@H99 ~]# date
Thu Feb  2 16:48:38 JST 2012

I've created all the folders in the script I provided in the post above, but how do I create a subsequent directory according to the next month

e.g 03 for March, 04 for April...

So the end results would be like this

  1. all the *history files from /var/log/user_history/ dumped into something like this:
/var/log/user_history/old_logs/02/*gz
/var/log/user_history/old_logs/03/*gz
/var/log/user_history/old_logs/04/*gz

You can do like this for the Destination Directory:

#!/bin/bash
 
OLD_HIST_DIR="/var/log/user_history/old_logs"
HIST_DIR="/var/log/user_history"
 
MNTH_DEST_DIR="/var/log/user_history/old_logs/$(date +'%m')"
# date +'%m' gives number corresponding to the current month in 01,02,...11,12 fashion
 
mkdir -p "${MNTH_DEST_DIR}"  "${OLD_HIST_DIR}" # This will create the directory if not present
 
cp -p ${HIST_DIR}/*history ${OLD_HIST_DIR}
 
gzip -9 ${OLD_HIST_DIR}/*history

mv ${OLD_HIST_DIR}/*.gz  ${MNTH_DEST_DIR}

hang on, let me try this out on my DEV

For some reason I am getting error and the zipped files are being stored in /var/log/user_history/old_logs/ instead of /var/log/user_history/old_logs/02

The error:

[root@H99 02]# /usr/local/bin/testing
/usr/local/bin/testing: line 7: fg: no job control
mv: `/var/log/user_history/old_logs/d12adm_history.gz' and `/var/log/user_history/old_logs/d12adm_history.gz' are the same file

the script:

[root@H99 old_logs]# more /usr/local/bin/testing
#!/bin/bash

OLD_HIST_DIR="/var/log/user_history/old_logs"

HIST_DIR="/var/log/user_history"

MNTH_DEST_DIR="/var/log/user_history/old_logs/$(date +`%m`)"

cp -p ${HIST_DIR}/*history ${OLD_HIST_DIR}

gzip -9 ${OLD_HIST_DIR}/*history

mv ${OLD_HIST_DIR}/*.gz ${MNTH_DEST_DIR}
[root@H99 old_logs]#

It would be nice if you can sentence your request properly.

I have C Shell and Bash Shell users, whose .cshrc and .bashrc are modified as such

C Shell

set histfile=/var/log/user_history/db2s12_history

Bash Shell

export HISTFILE=/var/log/user_history/db2ash_history
