-
GNU bash, version 4.3.48(1)-release (x86_64-pc-linux-gnu) These shell commands are defined internally. Type `help' to see this list. Type `help name' to find out more about the function `name'. Use `info bash' to find out more about the shell in general. Use `man -k' or `info' to find out more about commands not in this list. A star (*) next to a name means that the command is disabled. job_spec [&] history [-c] [-d offset] [n] or history -anrw [filename] or history -ps arg > (( expression )) if COMMANDS; then COMMANDS; [ elif COMMANDS; then COMMANDS; ]...
