diff

Compare files and directories.

• Compare files:

diff {{file1}} {{file2}}

• Compare files, ignoring white spaces:

diff -w {{file1}} {{file2}}

• Compare files, showing differences side by side:

diff -y {{file1}} {{file2}}

• Compare directories recursively:

diff -r {{directory1}} {{directory2}}

• Compare directories, only showing the names of files that differ:

diff -rq {{directory1}} {{directory2}}
