[SOLVED] rename as download wget sequentially bash

ytd_usr · 12-30-2015, 01:52 PM

Greetings. I am a Linux newbie and to this forum.So please go easy on me.
I have txt files in which urls are placed per line. I can download them using wget -i option. But since the links are random, wget puts default names, but after downloading i cant make head or tails of the files. but the urls are of lets say a show's video serially, i.e url1 is for episode1 and so on. since i have many urls, its a pain to rename each using wget's "-o" option. Since i dont know pretty much nothing about bash scripting, could anyone help me? I need wget to read episode 1's url, rename it to show_ep1.
eg. wget -o 'show-ep1' https://show/ep1.mp4 And so on.

Suggestions and modification of this question to support this forums guidelines(if necessary are appericiated)

use a while loop?

Code:

incr=1; while read i; do wget "$i" -O ep$incr; incr=$((incr+1)); done < txt_file

Code:

incr=1
while read i 
  do 
    wget "$i" -O ep$incr
    incr=$((incr+1))
done < txt_file

Hello Sefyir. I used your solution and it works,but still names the downloaded files to default url. Below is the output:

Connecting to r1---sn-h557snes.googlevideo.com (r1---sn-h557snes.googlevideo.com)|74.125.169.102|:443... connected.

0K .......... .......... .......... .......... .......... 0 94.8K 13m24s

I want "Saving to:XLMWgHCuIX_dSIAzdnHTTHZYr2pqd2VRjrwhPbWn5w=m18 " to be replaced with 'ep1', read next url, rename it as 'ep2' and so on. Is it possible?
And also can you tell me what "i" used in the script. If it is start number, then i am not able to input it.

ytd_usr, please open a terminal and enter "man wget".
if you have a look at the command line option, you will find one that enables you to define a name for the output file.
it seems sefyir used the wrong option ( -o ).
your task: find the right one.
then the script will work.

about "while read i": it reads the contents of the txt_file line by line, so $i always contains one url.

Hello there ondoho. You were right. In Sefyir's "-o" should be "-O". It then works perfectly> Thank You for your input. You both have been of great help

. For future users, i will paste the modified script ->

incr=1
while read i
do
wget "$i" -O ep$incr
incr=$((incr+1))
done < txt_file

Please use [code][/code] tags around code to maintain indentation and readability

Your code could be simplified a little too:

Code:

incr=1
while read url
do 
  wget "$url" -O ep$((incr++))
done < txt_file

I renamed 'i' as well to make it a little clearer what is happening

Yes - I did use the wrong option. I edited mine as well.
