file_manipulation:warp:3dcc9
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 ${old_text}. Here,-r
stands for "recursive" (search subdirectories), and-l
stands for "list" (display filenames instead of matching lines). -
| xargs
: The pipe character "|" is used to redirect the output of the previous command to the next command. In this case, it passes the list of filenames returned bygrep
to thexargs
command. -
sed -i '' 's/${old_text}/${new_text}/g'
: Thesed
command is a stream editor that performs text transformations. Here, it is used with the following options:-i ''
: This option modifies the files in-place, i.e., the changes are made directly to the files.'s/${old_text}/${new_text}/g'
: This is the substitution expression used bysed
. 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.
