bash-commander

Looks through your .bash_history file to give you a report of your most used commands, and suggests some possible aliases you could use.

Note that if your HISTCONTROL environment variable is set to erasedups this program would have little use. Also, by default your .bash_history is updated only when your bash session ends. Type history -a to update your .bash_history file with your current history.

Takes an optional parameter -n N, which causes the program to display your top N most used commands.

Sample Output

Your top 10 most used commands:
 #1:    vim (143)
 #2:    ./m.sh (63)
 #3:    vim m.sh (56)
 #4:    vim ccsh.sh (53)
 #5:    f (32)
 #6:    ./ccsh.sh (30)
 #7:    echo (25)
 #8:    source ccsh.sh (24)
 #9:    source (24)
 #10:   vim blah (21)

Here are some aliases, and the amount of characters typed you would save per alias:
 vim -> v (2 characters / 286 total)
 ./m.sh -> m (5 characters / 315 total)
 vim m.sh -> vm (6 characters / 336 total)
 vim ccsh.sh -> vc (9 characters / 477 total)
 f -> f (0 characters / 0 total)
 ./ccsh.sh -> c (8 characters / 240 total)
 echo -> e (3 characters / 75 total)
 source ccsh.sh -> sc (12 characters / 288 total)
 source -> s (5 characters / 120 total)
 vim blah -> vb (6 characters / 126 total)

However, if all the aliases were in place, you would save 1883 characters in all - or about 32.4096385542% of your total bash history.
