Recursive search and replace in text files on Mac and Linux

Question

In the linux shell  the following command will recursively search and replace all instances of  this  with  that   I don t have a Linux shell in front of me  but it should do    find   -name    txt  -print   xargs sed -i  s this that g    What will a similar command on OSX look like

Whenever I type this command I always seem to hose it up, or forget a flag. I created a Gist on github based off of TaylanUB's answer that does a global find replace from the current directory. This is Mac OSX specific.

It's nice because now I just pop open a terminal then copy in:

curl -s https://gist.github.com/nateflink/9056302/raw/findreplaceosx.sh | bash -s "find-a-url.com" "replace-a-url.com"

You can get some weird byte sequence errors, so here is the full code:

#!/bin/bash
#By Nate Flink

#Invoke on the terminal like this
#curl -s https://gist.github.com/nateflink/9056302/raw/findreplaceosx.sh | bash -s "find-a-url.com" "replace-a-url.com"

if [ -z "$1" ] || [ -z "$2" ]; then
  echo "Usage: ./$0 [find string] [replace string]"
  exit 1
fi

FIND=$1
REPLACE=$2

#needed for byte sequence error in ascii to utf conversion on OSX
export LC_CTYPE=C;
export LANG=C;

#sed -i "" is needed by the osx version of sed (instead of sed -i)
find . -type f -exec sed -i "" "s|${FIND}|${REPLACE}|g" {} +
exit 0

A version that works on both Linux and Mac OS X  by adding the -e switch to sed    export LC CTYPE C LANG C find   -name    txt  -print0   xargs -0 sed -i -e  s this that g

https   bitbucket org masonicboom serp is a go utility  i e  cross-platform   tested on OSX  that does recursive search-and-replace for text in files within a given directory  and confirms each replacement  It s new  so might be buggy   Usage looks like     ls test a  d  d2 z   cat test z hi     serp --root test --search hi --replace bye --pattern                              test z  replace hi with bye   y  n   y   cat test z bye

I used this format - but   I found I had to run it three or more times to get it to actually change every instance which I found extremely strange   Running it once would change some in each file but not all  Running exactly the same string two-four times would catch all instances   find   -type f -name    txt  -exec sed -i    s thistext newtext

The command on OSX should be exactly the same as it is Unix under the pretty UI

OS X uses a mix of BSD and GNU tools  so best always check the documentation  although I had it that less didn t even conform to the OS X manpage     https   web archive org web 20170808213955 https   developer apple com legacy library documentation Darwin Reference ManPages man1 sed 1 html  sed takes the argument after -i as the extension for backups  Provide an empty string  -i     for no backups   The following should do   LC ALL C find   -type f -name    txt  -exec sed -i    s this that        The -type f is just good practice  sed will complain if you give it a directory or so  -exec is preferred over xargs  you needn t bother with -print0 or anything  The      at the end means that find will append all results as arguments to one instance of the called command  instead of re-running it for each result   One exception is when the maximal number of command-line arguments allowed by the OS is breached  in that case find will run more than one instance

None of the above work on OSX   Do the following   perl -pi -w -e  s SEARCH FOR REPLACE WITH g     txt

This is my workable one  on mac OS X 10 10 4  grep -e  this  -rl     xargs sed -i     s this that g    The above ones use find will change the files that do not contain the search text  add a new line at the file end   which is verbose
