Bash Script renaming

beast12 · 01-10-2014, 02:27 AM

Hello all!

I would like to rename txt files in a folder to the last word of the first line IN the txt file.
This is what I have now:

Code:

name_check=$(cat info*.txt | head -1 | awk '{ print $NF }')

for filename in info*
do
        mv $filename $name_check
done

The info*.txt are the orignal files. They originate from a api call from ovirt. So I really need to change the file names info*.txt to the server name which is located on the first line as extracted with the name_check. With all my fingers crossed :-), I hope somebody can help me out here :-)

You have to put getting the new filename inside the loop:

Code:

for filename in info*
do
  name_check=$(head -1 "$filename"| awk '{ print $NF }')
  mv -v "$filename" "$name_check"
done

So we got rid of the useless cat, lets do the same with head:

Code:

awk 'NR==1{print $NF}' "$filename"
