It can get tricky to recursively look for specific text in the files that you care about in the locations that you care about. We will show you how.

The general syntax is:

find . \( -name node_modules -prune \) -o -iname "filenamewildcard*" -type f -exec grep -i -H "wordmatch1\|wordmatch2" {} \;

The output can be quite big, so if you are only interested in seeing the unique filename hits you should pipe the output through the following:

cut -d":" -f1 | sort -u

Bulk String Replace in Files

While sed is probably the most popular tool that is used, it gets tricky when using bulk search/replace using find. The following is the suggested method:

create a script called replace.sh with the following content:

cat $1 | sed 's/stringtosearch/replacement/g' > ../$1

mv ../$1 $1

you can then use find to launch the script:

find . -iname "files" -exec ./replace.sh {} \;

SED can behavace unexpectedly for doing the changes in palce with the filename.

Get rid of ^M in text files

This can happen when you work in a mixed environment. To fix this, you should convert DOS line endings to Linux line endings. For example using vim:

set ff=unix

%s/\r//g

As a side note, if you are using Visual Studio, please be sure to use .editorconfig at the solution root with the following:

endofline = lf
