How can I make a list with most used commands in terminal?
I know that this question may be unuseful for any future proposals for some of us, but even like this, the list can be useful when we don't remember a command used once or some times in the past, when we can search at the end of this list.
We will use the records from .bash_history file to do this. The next command will give you a list of all commands in order that you used them most often:
history | awk 'BEGIN {FS="[ ]+||"} {print $3}' | sort | uniq -c | sort -nr
If you want only top 10, you must to add head at the command above:
history | awk 'BEGIN {FS="[ ]+||"} {print $3}' | sort | uniq -c | sort -nr | head
To get a specific top, for example top 5, use head with -n 5 option:
If you want the list in reverse order (top with the rarely used commands), don't use r oprion for second sort:
history | awk 'BEGIN {FS="[ ]+||"} {print $3}' | sort | uniq -c | sort -n
And finally to get a list with the commands used once for example, use grep ' 1 ' (change 1 with the desired number):
history | awk 'BEGIN {FS="[ ]+||"} {print $3}' | sort | uniq -c | grep ' 1 '
To deal with sudo commands (like sudo vim foo), instead of just {print $3} in the awk command, use:
{if($3 ~ /sudo/) print $4; else print $3}
So the entire command would look like:
history | awk 'BEGIN {FS="[ ]+||"} {if($3 ~ /sudo/) print $4; else print $3}' | sort | uniq -c | sort -nr
For example:
$ history | awk 'BEGIN {FS="[ ]+||"} {print $3}' | sort | uniq -c | sort -nr | head
284 vim
260 git
187 find
174 man
168 echo
149 rm
134 awk
115 pac
110 sudo
102 l
$ history | awk 'BEGIN {FS="[ ]+||"} {if($3 ~ /sudo/) print $4; else print $3}' | sort | uniq -c | sort -nr | head
298 vim
260 git
189 find
174 man
168 echo
153 rm
134 awk
115 pac
102 l
95 cd
You can see the jump in counts for vim, rm, etc.
