Linux – How to use sed, perl to rename files and its contents with a particular pattern in a given directory

findlinuxperlsed

Given a directory "Centos1" which has few files named Centos1.x, Centos1.y, Centos1.z and these files also has "Centos1" in their contents. Using a single command ( using find, sed, perl -pie ) how can I get them renamed to "Centos2" for all occurence of "Centos1"
Here are the content of Centos1 directory.

Centos1.nvram      Centos1-s005.vmdk  Centos1.vmsd  vmware-2.log
Centos1-s001.vmdk  Centos1-s006.vmdk  Centos1.vmx   vmware.log
Centos1-s002.vmdk  Centos1-s007.vmdk  Centos1.vmxf
Centos1-s003.vmdk  Centos1-s008.vmdk  vmware-0.log
Centos1-s004.vmdk  Centos1.vmdk       vmware-1.log

NOTE: I want to have "Centos1" replaced with "Centos2" inside all files too if it's present.

I ran the below mentioned command after I changed to "Centos1" directory

find . -type f -exec sed -i 's/Centos1/Centos2/g' {} +

But it didn't help. Any input ?

You can use the rename command to do the renaming

rename Centos1 Centos2 *

or if you have the perl rename

rename 's/Centos1/Centos2' *

Your find command should change all occurences of Centos1 to Centos2 so you could wrap them in a simple script to make it a single command.

#!/bin/bash
rename Centos1 Centos2 *

find . -type f -exec sed -i 's/Centos1/Centos2/g' {} +

Linux – How to use find command to delete files matching a pattern

I generally find that using the -exec option for find to be easier and less confusing. Try this:

find . -name vmware-*.log -exec rm -i {} \;

Everything after -exec is taken to be a command to run for each result, up to the ;, which is escaped here so that it will be passed to find. The {} is replaced with the filename that find would normally print.

Once you've verified it does what you want, you can remove the -i.

I think this could do it:

find /home \( -name "*.html" -o -name "*.php" \) -exec sed -i.bak 's/<script.*PaBUTyjaZYg.*script>//g' \{\} \;

From the comment "to delete all files has numbers in thier name and extension .php"

find /home -name "*[0-9]*.php" -exec rm \{\} \;

But first, run it with echo instead of rm, to make sure you don't delete something you don't want to delete.
