I have number of files and a set of find and replace text combinations.

For example, I have a set of find text and replace text like this,

  • find - "margin" replace with "new_margin"
  • find - "color" replace with "color_primary"
  • find - "xxx" replace with "zzzz"
  • find - "rre" replace with "768"

I have nearly 100 of such combinations, i need to find all "find texts" and replace it with corresponding replace text.

How can I do this easily?

Is there any tool to do this?

    Could you please provide the input, I mean your find/replace sets. Are they saved in a file or how ?! – pLumo May 9 '19 at 7:35

to substitute the text inside the files in a single shot you can use sed:

sed -i -e 's@margin@new_margin' -e 's@color@color_primary@' -e 's@xxx@zzz@' -e '@rre@768@' /path/to/files/*

-i option say to sed to perform modification in file without print

-e say to sed have more string to be find and substituted

s@ says the '@' is the separator for string_to_find and replacement_string

the latest is the path where the file are, if they are all in one location you can perform this command once.

!!!Execute a backup of your file ALWAYS before make modification with sed in file directly!!!


Thanks to @steeldriver which says in the comment to not modify the source file with sed adding a suffix to the -i options

-i[SUFFIX], --in-place[=SUFFIX]


sed -i_edited 's@margin@new_margin' /path/to/files/examplefile

will result with a new file modified called examplefile_edited

    They could make a backup automatically by providing a suffix argument to the -i option – steeldriver May 9 '19 at 11:42
  • Upvoted and upflagged all around for backup suggestions. Most answers never suggest that. – WinEunuuchs2Unix May 9 '19 at 12:51
