Update all folders that have .git

find . -maxdepth 1 -type d -print -execdir git --git-dir={}/.git --work-tree=$PWD/{} pull origin master \;

• find . searches the current directory
• maxdepth 1 for a maximum depth of one sub-directory
• type d to find directories, not files
• execdir {} ; runs a custom command for every find
• git --git-dir={}/.git --work-tree=$PWD/{} pull git pulls the individual directories
