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="[ \t]+|\\|"} {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="[ \t]+|\\|"} {print $3}' | sort | uniq -c | sort -nr | head

To get a specific top, for example top 5, use head with -n 5 option:

Top 5 commands

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="[ \t]+|\\|"} {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="[ \t]+|\\|"} {print $3}' | sort | uniq -c | grep ' 1 '

Below command will also list the top 10 most frequently used terminal commands,

history | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head

Command to list all the commands which are most oftenly used in terminal,

history | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn
