How so, because it shows useless information or because it does so in a non dynamic way?
I made a little script to encrypt a message via GPG and send it as an email. I'll post it tomorrow if the thread lasts.
curl --silent 'http://wttr.in/London' | head -7

Don't use backticks (``), use $().
Always quote variables.
It's a good idea to use -- when you work with rm and variables, this avoids problems when the variable changes to problematic things like "-rf"-
>>55205624
>use printf
>>55205782
Don't be retarded. printf is more portable and more secure than echo. Some echo implementations even have different or missing options.

>>55205763
Why? $() is supposed to be slower, because it spawns a subshell.
The variables passed to rm are guaranteed to be fine, because they don't depend on user input.
>>55205823
No, $() executes just like ``, but makes nesting more easy.
() (without $) spans a subshell.

Are you employed?
>>55205888
Yeah I am, even if I wasn't, writing scripts and learning linux/unix commands is still an infinity more productive hobby that playing video games for example.
>>55205902
Can't argue against that.
I myself am writing some low tier bash scripts, mostly one purposed stuff though.
I asked cause I remember you from years ago in the desktop threads (you're the guy with openbox / lemonbar, right?) and IRC where it seems you were living at your parents place hence my strange question.
Your thick titleless titlebars were one of my inspirations tho, I guess I should thank you for that.
Out of curiosity, what's your job?

You blew it.
>>55205884
too bad its for the fish shell and it doesnt work in bash or zsh :DDDD
>>55206090
It has a shebang so it works in every shell, that's like saying python scripts don't work when you use bash. You just need to have fish installed.
