Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
history | awk '{print $2}' | sort | uniq -c | sort -rn | head
history | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head > /tmp/cmds | gnuplot -persist <(echo 'plot "/tmp/cmds" using 1:xticlabels(2) with boxes')

Plot your most used commands with gnuplot.

history | awk '{a[$'$(echo "1 2 $HISTTIMEFORMAT" | wc -w)']++}END{for(i in a){print a[i] " " i}}' | sort -rn | head

If you use HISTTIMEFORMAT environment e.g. timestamping typed commands, $(echo "1 2 $HISTTIMEFORMAT" | wc -w)

gives the number of columns that containing non-command parts per lines.

It should universify this command.

HISTTIMEFORMAT='' history | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head > /tmp/cmds ; gnuplot -persist <<<'plot "/tmp/cmds" using 1:xticlabels(2) with boxes'

This alternative cleans HISTTIMEFORMAT environment variable and calls gnuplot just after /tmp/cmds is closed, to avoid some errors.

history | awk '{if ($2 == "sudo") a[$3]++; else a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head

Know a better way?

If you can do better, submit your command here.

What others think

It didn't work properly for me I used "history -$HISTSIZE" against just "history" to sue the full history and not only the 10th firsts.

my correction is then

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

since i got dates on my commands this one works better for me using the 4th column

history | awk '{a[$4]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head

Comment by bbelt16ag 326 weeks and 4 days ago

use this! more portable

history | awk '{a[$'`echo "1 2 $HISTTIMEFORMAT" | wc -w`']++}END{for(i in a){print a[i] "\t" i}}' | sort -rn | head

Comment by bandie91 323 weeks ago

history | sort -k2,3 | uniq -f 1 -c | sort -rn | head

Arranges it in columns, and with a variable number of results. Use $ mostused NUMBERTOSHOW

mostused() { history | awk '{a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | ( echo "USES COMMAND" && head -n $1 ) | column -t; }
