Shell script to change files content on multiple git repository

Continuing last post, change content in multiple files, I made another script to change multiple files on each git repository and push the code.

1. Make folder list in array

#!/bin/sh

array=( site1 site2 site3 )

2. For each loop for each sites

for site in "${array[@]}"
do
  #some command
done

3. Replace content in each file

cd ~/home/"$site"/
rpl ".title" ".h1_title" ~/home/"$site"/css/common.css

4. Commit the changes

git pull
git add .
git commit -am 'title changed to h1 title on css file'
git push

5. This is the final code.

#!/bin/sh

array=( site1 site2 site3 )

for site in "${array[@]}"
do
  cd ~/home/"$site"/
  rpl ".title" ".h1_title" ~/home/"$site"/css/common.css
  git pull
  git add .
  git commit -am 'title changed to h1 title on css file'
  git push
done

This is especially useful when I have many sites with same structure.

 

Change content text on multiple files using shell script

When I want to change text in several files, it’s hard to open each single file and replace.
So I made one shell script to do the job.
Here’s one example using sed command.

find /home/user/directory -name \*.* -exec sed -i “s/search_text/replace_text/g” {} \;

BTW, it’s hard to remember. Also if I want to change including special character, it’s more harder. like this one. <?php echo $text;?> 

I searched for easy way and found good command. rpl – replace string in files

It’s really easy to use. If you don’t have rpl installed, install it using brew.

$ brew install rpl
rpl "<?php echo $search_text;?>" "<?php echo $replace_text;?>" /home/user/directory

Amazing! I don’t need to remember complicate command line.
However, I want to change in multiple files at the same time, moreover I would like to make easier input without change core programming.

#!/bin/sh
echo "Please enter search: "
read search_variable
echo "Search: $search_variable"
echo "Please enter replace: "
read replace_variable
echo "Replace: $replace_variable"

This bash script will get user input, both find and replace text.

for file in `find . -type f`
do
    rpl "$search_variable" "$replace_variable" $file
done

And this will find all files and replace text. Here’s final code. Save to replace.sh file in good place.

#!/bin/sh
echo "Please enter search: "
read search_variable
echo "Search: $search_variable"
echo "Please enter replace: "
read replace_variable
echo "Replace: $replace_variable"


for file in `find . -type f`
do
    rpl "$search_variable" "$replace_variable" $file
done

One more, I would like to use this command from every where.

alias replace="~/home/shell/replace.sh"

Put this in the .bash_profile, so the comman is available from any where.
