Fun with history - pranomostro - 27-10-2015
Hi y'all,
yesterday I played around with the history function
in different shells.
First, I wanted to know how many unique shell commands I had used during
the last month:
Code:
» history | wc -l
6840This works because my main shell (fish) does not show duplicate shell commands.
Interesting. I thought this would be more, provided that I am nearly exclusively using
the shell.
Next I wanted to take a look at the longest command lines I ever wrote:
Code:
» history | awk '{ print length() " " $0 }' | sort -n | sed 's/^[0-9]\+ //' | tail -5Code:
mv "Beißkraft\ -\ Bisskraft\ -\ Report\ -\ Beißkraft\ Übersicht\ -\ Bisskraft\ Übersicht\ -\ Beißkraft\ Vergleich\ -\ Extremes\ und\ Rekorde\ aus\ aller\ Welt" beißkraftvergleich
mv Beißkraft\ -\ Bisskraft\ -\ Report\ -\ Beißkraft\ Übersicht\ -\ Bisskraft\ Übersicht\ -\ Beißkraft\ Vergleich\ -\ Extremes\ und\ Rekorde\ aus\ aller\ Welt.html beißkraftvergleich.html
for i in (l); cd $i; for i in (l); set j (echo $i | tr A-Z a-z | tr ' -' '_' | tr -d "'()#&!?,*\$|~`+%[]^<>=/{}:@" | sed 's/__\+/_/g' | sed 's/^[0-9][0-9]_//'); echo $j; end; cd ..; end | p
for i in (l); cd $i; for i in (l); set j (echo $i | tr A-Z a-z | tr ' -' '_' | tr -d "'()#&!?.*\$|~`+%[]^<>=/{}:@" | sed 's/__\+/_/g' | sed 's/^[0-9][0-9]_//'); echo $j; end; cd ..; end | p
for i in (l); cd $i; for i in (l); set j (echo $i | tr A-Z a-z | tr ' -' '_' | tr -d "'()#&!?,*\$|~`+%[]^<>=/{}:@" | sed 's/__\+/_/g' | sed 's/^[0-9][0-9]_//'); mv "$i" $j; end; cd ..; end | pAlso, I looked what my most used commands were:
Code:
» history | tr '|' '\n' | sort | field 1 | uniq -c | awk '$2~/^[a-z]+$/' | sort -n | tail -20The result was interesting:
Code:
109 sudo
124 ag
125 git
127 cat
133 less
141 play
143 man
153 tr
154 sts
163 sed
174 uniq
179 r
195 cd
199 awk
214 mv
229 cd
243 field
326 sort
354 cd
463 cat'play' is a wrapper script for ogg123, 'sts' is a command to start the sam text editor in the background,
'r' is a script that moves files to ~/trash, and 'field NUM' prints the NUMth field in the input, for
every line. Everything else is standard, I suppose.
It seems like I mostly use the shell for printing stuff, going somewhere and sorting things.
Maybe I should make an alias for cat, like 'c' or something...
A slightly changed version shows the frequency of commands at the beginning of command lines:
Code:
» history | field 1 | sort | uniq -c | sort -n | tail -20Here, the result is quite different:
Code:
71 md
72 du
72 mupdf
86 cp
87 pn
92 less
98 history
101 pipes
107 for
109 sudo
123 ag
141 play
169 l
214 mv
220 sts
227 man
426 git
433 r
696 cat
792 cdI still seem to use cd and cat a lot, but it also looks like I enjoyed pipes (for some period).
'pn' is an alias for the potion interpreter, to make it easier to type, and 'md' is an alias for mkdir.
So, that's all I've got so far. If you want to share parts of your history, feel free to do so.

That's an interesting analyze of history.
You could extract the most used commands an make a boostrap script to set them up on your new installs.
That way you won't get lost.
