find explained

Command Breakdown:
 1. '.' => search path starting at current directory marked by ' . '
 2. -name => set find match name (in this case all files that end with .gappedPeak)
 3. -exec => execute the following command on every match
 4. sh -c => 'exec' creates an independent shell environment for each match
 5. mv "$1" "${1%.gappedPeak}.bed" => mv first variable (denoted by $1), which is the current file name, to new name. Here I do a substring match and delete; so take first var again, $1 and use % to delete .gappedPeak from the string. The .bed at the end just concatenates the remaining variable, which is now just test#, with .bed, creating the new test#.bed filename.
 6. The underscore is a placeholder for $0
 7. The {} is replaced by each (*.gappedPeak) filename found by the find command, and becomes $1 to the sh command.
 8. \; marks the end of the -exec command.  You can also use ';' or ";".

find . -name "cover.1*" -exec sh -c 'echo "$1" ".${1%.1.jpg}.jpeg"' _ {} \;
