I have this list of download links.

It turns out the download daemon used the last entry as file name. 

-rwxrwxrwx 1 gottsch gottsch 593984618 Mar 23 14:56  29629751
-rwxrwxrwx 1 gottsch gottsch 632598628 Mar 24 14:57  29640134
-rwxrwxrwx 1 gottsch gottsch 535594310 Mar 25 14:55  29650516

-rwxrwxrwx 1 gottsch gottsch 534740104 Mar 31 14:56  29709747

I now want to rename the files to something more meaningful.

Using awk :

awk 'BEGIN {FS="/"} {print "mv ",$12,$10}' wunschliste.txt.fertig

I am expecting something like :

mv 29709747 Babylon_5_20.03.31_19-10_tele5_65_TVOON_DE.mpg.HQ.avi

However (unexpectedly) I get:

$ awk 'BEGIN {FS="/"} {print "mv ",$12,$10}' wunschliste.txt.fertig
 Babylon_5_20.03.31_19-10_tele5_65_TVOON_DE.mpg.HQ.avi
 Babylon_5_20.03.30_19-10_tele5_65_TVOON_DE.mpg.HQ.avi
 Babylon_5_20.03.27_19-10_tele5_65_TVOON_DE.mpg.HQ.avi
 Babylon_5_20.03.26_19-10_tele5_65_TVOON_DE.mpg.HQ.avi
 Babylon_5_20.03.25_19-10_tele5_65_TVOON_DE.mpg.HQ.avi
 Babylon_5_20.03.24_19-10_tele5_65_TVOON_DE.mpg.HQ.avi
 Babylon_5_20.03.23_19-10_tele5_65_TVOON_DE.mpg.HQ.avi

Well, where is my 'mv' ? Where is the first argument?

Edit. there was an ask for this cmd:

head -1 wunschliste.txt.fertig | od -c

    Try this first: `dos2unix wunschliste.txt.fertig`. – Cyrus May 01 '20 at 05:09

    mostly likely this is the issue [Why does my tool output overwrite itself and how do I fix it?](https://stackoverflow.com/questions/45772525/why-does-my-tool-output-overwrite-itself-and-how-do-i-fix-it) – Sundeep May 01 '20 at 05:10
  • Can you please share output of `head -1 wunschliste.txt.fertig | od -c` – Digvijay S May 01 '20 at 06:40
  • Not the issue but make it `print "mv -- \047" $12 "\047 \047" $10 "\047"` so the `mv` will succeed no matter what characters are in your strings. The way you have it written above to generate a mv command without quotes around the file names would cause the mv to fail given various characters in your strings, contents of the directory you run it from, environment settings, etc. – Ed Morton May 01 '20 at 12:23
  • Why do you want to it this when this can be simply done: while read v_read do v_curr_file_nm=`echo $v_read | awk -F "/" '{print $12}'` v_updt_file_nm=`echo $v_read | awk -F "/" '{print $10}'` mv ${v_curr_file_nm} ${v_updt_file_nm} done < wunschliste.txt.fertig – Divyaansh Bajpai May 05 '20 at 12:15
