a shell builtin command in watch?

a shell builtin command in watch?

(OP)

because I can't find any command replacement to the built-in 'history' command, I'd like to ask you if can use watch + history to continuously view history changes with date:

root@test:~# history|tail -2
598 17/11/15 14:23:48 :: HISTTIMEFORMAT="%d/%m/%y %T :: "
599 17/11/15 14:23:54 :: history|tail -2

what I tried to do is:

# watch -t -d=cumulative history

but it fails with error:

sh: 1: history: not found

anyway to use history with watch comamnd?

RE: a shell builtin command in watch?

If you want to just get commands that end up in the history, with time stamp, as they happen, this should get you close...

CODE

tail -f ~/.sh_history | (unset IFS; while read LINE; do print "$(date '+%Y%m%d:%H%M%S'): ${LINE}"; done) 

Output looks like this...

CODE

20151117:110700: ls -la
20151117:110941: man history
20151117:110948: ls -la
20151117:111013: find . -name '*.sql' -ls
