Rename the multiple files which matching certain string - linux

Ex:

 test1_test3.txt 

 test1_test4.txt 

 $ ls * | sed -e 'p;s/test1/XYZ/' | xargs -n2 mv

linux - excluding certain files from the directory and printing

ls /etc/sudoers.d/ --ignore="*.*" --ignore="*~"| xargs cat

CHECK BACKEND ENGINES STATUS

/appian_home/appian/services/bin/status.sh -p $APPIAN_PW -c


If Services Stop abruptly then we need to do perform checkpoint procedure.

How to rename weblogic domain name

Changing weblogic domain name is possible with modifying certain files under your domain.

In this exercise – I have renamed from wl-lstba to wl-bstqa

1) Take complete backup of your domain

2) Copy old domain name folder to new domain name
cp -rp wl-lstba wl-bstqa

3) Search all files which contains lstba in newly copied folder
[wlapp@Server1 server1034]$ pwd
/pae/Server1/weblogic/dst/server1034/wl-bstqa
grep -rl lstba *

4) Replace lstba with bstqa name


grep -rl lstba . | xargs sed -i -e 's/lstba/bstqa/'


Ensure none of the files are having base_domain



[wlapp@Server1 server1034] grep -r lstba *




5) Restart the JVM's to verify servers are coming up.

Creating Volume group and logical Volume

pvcreate /dev/sdd ( It should run only once)

vgcreate rhel03 /dev/sdd ( Creating Volume group here and assigning to /dev/sdd)

lvcreate -l 100%FREE -n u03 rhel03 ( Creating logical volume group u03 and assigning to volume group rhel03)

lvscan (to check the logical volumes)

mkfs.xfs -f /dev/rhel03/u03 ( formatting the disk)

/dev/mapper/rhel03-u03 /u03 xfs defaults 1 2
mount /u03

Moving home directory in linux

Username: test
Environment : Linux

$usermod -d /usr/test -m test

## Here "test" is a user and /home/test is directory which will move from /home/test to /usr/test.

Ansible

Linux User Administration

Adding a user with UID to the group

useradd -c "comment" -u 801 -g group username;
chage -I -1 -m 0 -M 99999 -E -1 username;


Modify a existing user group
usermod -a -G group username

Removing a user from GROUP

gpasswd -d username group
