baby's first program

im making a little script to automagically download all of my avatars on forumotion

look at this quality shit:

Code:

export itsautomated=0
while true; do
export itsautomated=`expr $itsautomated + 1`
if [ $itsautomated == 100 ]; then exit; else wget http://r29.imgfast.net/users/3417/17/08/55/avatars/1-$itsautomated.png; fi
done


tabs are for pussies

it works perfectly though

what language is that

bash

so it's not really a program since that's just a shell

I have no idea what it says.

breakdown:

export itsautomated=0 <-- "export" is a command that sets an environment variable; so in this case, the number zero (but you can make it anything you want, you could have it say "ammy is kool" but that wouldn't work in this situation)


while true; do <-- loop whatever's down there, once it reaches "done" it just repeats the line underneath until it gets to done again, and then do it over and over

export itsautomated=`expr $itsautomated + 1` <-- again sets the "itsautomated" variable, uses the program "expr" (expression) to add the number 1 to the variable

if [ $itsautomated == 100 ]; then exit; else wget https://7img.net/users/3417/17/08/55/avatars/1-$itsautomated.png; fi <-- once the number hits 100, cancel the loop and exit the program, if it's still in the range of 1-99, use the program "wget" (which downloads webpages) to download from the list of my avatars with the variable $itsautomated filling the 1-*** spot, so it would be avatars/1-1.png, avatars/1-2.png until it reaches 99

shell scripts are easy to understand when you understand what every program does

if you only need to do it 100 times then why not just for i<100

there isn't really a huge difference between the two depending on what you use, it's 6 in one hand and half a dozen in the other. i just went with "wait til it climbs to 100 and then kill the program" because thats what im used to

im bored tonight so i redid this and made itsautomated.sh 2nd edition

Code:

export itsautomated=0
echo "UID?"
read sub
wget http://r29.imgfast.net/users/3417/17/08/55/avatars/$sub-$itsautomated.{png,jpg}
while true; do
export itsautomated=`expr $itsautomated + 1`
if [ $itsautomated == 100 ]; then rm `du -ah | grep 4.0K | egrep -i "png|jpg" | cut -f 2` && mkdir $sub && mv `ls |egrep -i "png|jpg"` $sub && exit; else wget http://r29.imgfast.net/users/3417/17/08/55/avatars/$sub-$itsautomated.{png,jpg}; fi
done

it is glorious

buy a thousand raspberry pis and run millions of that script

it has user input at the start i dont want to burn my fingers off

make robotic hands

stupid fucking thing breaks if you already have a directory

this opens up some possibilities for RTCity-tier statician bullshit

for example, running `md5sum * | cut -d" " -f 1 |sort | uniq -dc | sort` can show you what avatar is most commonly uploaded (although you cant see the filename)

recursive avatar sorting

md5sum `find . -type f` | cut -d" " -f 1 | sort | uniq -c | sort
