Perhaps this is a bash centric meme, and tcsh history gives the command in a different column. Ah yes, this works better:

history | awk '{a[$3]++} END{for(i in a){printf "%5d\t%s \n",a[i],i}}' | sort -rn | head

20 ./amhd
13 make
9 cd
7 python
6 ssh
5 svn
3 ls
3 history
2 gdb
1 scp

Running the same thing in the other terminal window gives me:

82 python
6 svn
5 cd
3 grep
2 ssh
1 rm
1 history

cd is remarkably lower on that list that it is on most people's.

From:

jhgowen.livejournal.com

well, I am running a Mac, so mostly I operate in the GUI. The main thing I drop down to the BSD Unix underpinnings and the bash shell for is to run a tightbinding atomistic simulation, which requires pico, tail, rm, touch, cp, the two ~/bin/ commands, and edit which opens any textfile in a GUI text editor. So I rarely have to cd or ls.

From:

I'm on a Mac too but I dislike the GUI. I have the sensation that its slower to work with than the command line+tab completion though its not something I've ever tested.

From: (Anonymous)

Strange, as the GUI is generally reckoned to be the strong point of the Mac. But for that specific operation, you're probably right.

Not sure how you would test in general that GUI and command line are faster than each other, as one does very different things with each. No GUI way to run a tightbinding simulation, no CLI way to process STM images.
Text-file editing possibly, then you get into the realms of personal taste. For me "edit foo.txt" on the CLI then editing in Text Wrangler is more efficient than using pico, but my friend Dave, who pretty much lives in vi and emacs, would tell me that he can edit text much faster with them.

P.S. If you have large bibliographies, check out BibDesk.

From:

purplecat

Well you could check which was faster for file system navigation with some sort of normalised test of task speed using.

I'm an emacs user, partly because I use applications written in emacs and then because of familiarity, but it is quite slow to open. Hence the prominence of less in my list - if I'm just looking at a file then less is much quicker.
