Currently, I have
grep -irl $schema $WORKDIR/ | xargs sed -i 's/'"$schema"'/EXI1/gI'
which doesn't work for filenames with spaces.
Any ideas, how to search and replace recursively for all files?
Thanks

This collection of sed and grep use cases might help you better understand how these commands can be used in Linux. Tools like sed (stream editor) and grep (global regular expression print) are powerful ways to save time and make your work faster.
Your terminal may show the file name with space escaped with backslash if you press tab key for the filename. Read a file with spaces in filename To use a filename with spaces in it, you can wrap it in quotes like this: cat "file name with spaces"
The one thing you'll notice that files in Linux usually do not contain names. Your teacher or colleague use underscore instead of spaces in file and directory names. It's not that you cannot use spaces in file names in Linux terminal. It's just that it creates additional pain and that's why you should avoid it wherever possible.
The g stands for global replace (meaning throughout the file). You can even change the servers’ regions in the file: This use case is more advanced. We’ll only remove comments ( #) from a file using sed:
Add the -Z (aka --null) flag to grep, and the -0 (also aka --null) flag to xargs.
This will output NUL terminated file names, and tell xargs to read NUL terminated arguments.
eg.
grep -irlZ $schema $WORKDIR/ | xargs -0 sed -i 's/'"$schema"'/EXI1/gI'
find with sed should work:
find $WORKDIR/ -type f -exec sed -i.bak "s/$schema/EXI1/gI" '{}' +
OR
find $WORKDIR/ -type f -print0 | xargs -0 sed -i.bak "s/$schema/EXI1/gI"
