If you use HISTTIMEFORMAT environment e.g. timestamping typed commands, $(echo "1 2 $HISTTIMEFORMAT" | wc -w) gives the number of columns that containing non-command parts per lines. It should universify this command. Show Sample Output
0history | awk '{a[$'$(echo "1 2 $HISTTIMEFORMAT" | wc -w)']++}END{for(i in a){print a[i] " " i}}' | sort -rn | head -
0history | awk '{if ($2 == "sudo") a[$3]++; else a[$2]++}END{for(i in a){print a[i] " " i}}' | sort -rn | head
-
This alternative cleans HISTTIMEFORMAT environment variable and calls gnuplot just after /tmp/cmds is closed, to avoid some errors.
-1HISTTIMEFORMAT='' 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'
