replacing filenames using pattern and find command

replace-filenames.md

find . -name '*.txt' -exec sh -c 'x="{}"; mv "$x" "${x//2010/2022}"' \;

Whats under the hood?

• find command finds the files that ending with *.txt using -name parameter
• -exec parameter executes move (mv) command for each found file
• second move argument ${x//2010/2022} replaces string 2010 with 2022 in file names using shell parameter expansion

Files before command:
