i just start to use Script bash on UNIX and i didnt find a solution to write the first command in the history which start , for example , with ls. If i write in the shell history !ls it works but when i'm going to create a script it wont work. This is my example code #!/bin/bash set -o | grep history set -o history #echo "HISTFILE is $HISTFILE" #history "!ls"; #history #!ls history #it works Another Question why echo "HISTFILE is $HISTFILE" print me only HISTFILE is ?? Thanks
