Command line tools every web dev needs to know

$ curl -I news.ycombinator.com HTTP/1.1 200 OK Content-Type: text/html; charset=utf-8 Cache-Control: private Connection: close Keep in mind that this will fire a HEAD request to the server which, depending on web server you use in development, may not return the exact header you'd get with GET (IIRC, Jetty used to do this). I like to use something like this in such situation: $ curl -s -D /dev/stderr news.ycombinator…

I rarely find I use curl's -s without its -S, e.g. -sS. It seems curl's design is flawed in its definition of -s; perhaps it's historic and it was too late to change it.

Also, typing. I am frequently amazed to see professional software developers with years of experience in the field, who only type using their two index fingers. You probably do not need to type 120 WPM to be an amazing programmer, but typing without looking at the keyboard is absolutely essential.

I used to be one of those. Until one day a colleague noticed and made a remark. Then I looked at other colleagues and realized my problem. I used http://www.gnu.org/software/gtypist/ to fix it.

The junk goes to stderr, so it won't impact anything but your screen when used from the command line. And sometimes (large transfers) you want that information. I think the default is sane. When you're using curl in a script you use -s, when you're using it interactively you want the diagnostics.

    $ curl -s does.not.exist; echo $?
    6
    $ curl -sS does.not.exist; echo $?
    curl: (6) Couldn't resolve host 'does.not.exist'
    6
    $

It's perhaps one of the effective filters while hiring. Not just the typing speed, but the general use of command line tools and keyboard shortcuts. Most good developers that I know are masters of the keyboard. They rarely ever touch the mouse.

Do you allow them to install their favorite editor? If someone watched me on Visual Studio without letting me install Viemu first, I'd look like an idiot.

I'm still trying, but it's demanding more discipline from me than I thought I'd need at first. It's hard to get rid of bad habits when they've already become muscle memory.
