‘history‘ command lists or saves previous entries in the history of the command line editing, or executes an entry.
Here you find ’usage by examples’:
history # show the complete history
history 5 # show last 5 entries in the history
history quiet 5 # show last 5 entries without entry numbers
history "hist.gp" # write the complete history to file hist.gp
history "hist.gp" append # append the complete history to file hist.gp
history 10 "hist.gp" # write last 10 commands to file hist.gp
history 10 "|head -5 >>diary.gp" # write 5 history commands using pipe
history ?load # show all history entries starting with "load"
history ?"set c" # like above, several words enclosed in quotes
hi !reread # execute last entry starting with "reread"
hist !"set xr" # like above, several words enclosed in quotes
hi !hi # guess yourself :-))
On systems which support a popen function (Unix), the output of history can be piped through an external program by starting the file name with a ’|’, as one of the above examples demonstrates.
