Find all text files with Linux line endings

Question

I want to use Windows line endings (CRLF) for all of my source files but sometimes Linux line endings get mixed in, e.g. when Git is not properly configured.

How can I easily find all text files which have Linux line endings (LF)?

Answer 1

A well readable solution using Cygwin is:

 find . -not -path '*/.*' -type f | xargs file | grep text | grep -v CRLF

Explanation:

• -not -path '*/.*': Filter out all directories starting with . (e.g. .git and .vs)
• -type f: Consider only files (not directories)
• xargs file: Apply file command to determine the file type
• grep text: Only consider text files (file includes string text for all of them)
• grep -v CRLF: Filter out files with Windows line ending

Note: To find all files with Windows line endings, just remove the -v:

find . -not -path '*/.*' -type f | xargs file | grep text | grep CRLF
