Strace all signals processes based on a name ( The processes already started... ) with bash built-in
Especially for sysadmins when they don't want to waste time to add -p flag on the N processes of a processname. In the old school, you did ; $ pgrep processname and typing strace -f -p 456 -p 678 -p 974... You can add -f argument to the function. That way, the function will deal with pgrep to match the command-line. Example : $ processname -f jrockit
