Recursively find and replace within a directory

grep

$ grep -rl ${old_text} ${file_path} | xargs sed -i '' 's/${old_text}/${new_text}/g'

try on your machine

This command is used to replace occurrences of a specific text string (${old_text}) with a new text string (${new_text}) in multiple files.

Let's break down the command:

grep -rl ${old_text} ${file_path}: This command searches for files within the specified file path that contain the text string ${old_text}. Here, -r stands for "recursive" (search subdirectories), and -l stands for "list" (display filenames instead of matching lines).
| xargs: The pipe character "|" is used to redirect the output of the previous command to the next command. In this case, it passes the list of filenames returned by grep to the xargs command.
sed -i '' 's/${old_text}/${new_text}/g': The sed command is a stream editor that performs text transformations. Here, it is used with the following options:
- -i '': This option modifies the files in-place, i.e., the changes are made directly to the files.
- 's/${old_text}/${new_text}/g': This is the substitution expression used by sed. It replaces all occurrences of ${old_text} with ${new_text}. The 'g' flag is used to replace all occurrences on each line, not just the first one.

Overall, this command searches for files containing ${old_text}, then using xargs it passes the filenames to sed to replace ${old_text} with ${new_text} in all the matching files.
