Problem with reading multiple lines from multiple files

Hi All,

I am having a problem while reading multiple lines from multiple files. I have two files in the directory sat test. File names are test1.txt & test2.txt. Contents of the files are:


[~/test]$ cat test1.txt
XYZ uniqueID ABC
DEF Price 800


[~/test]$ cat test2.txt
xyz uniqueID 900
def Price abc

i want my code to grep multiple particular word from these 2 or multiple files of same type & process accordingly. But the code seems to not be working for multiple lines.
Code is:

#Reading Multiple files

for file in ~/test/*; do
    while read -r line; do
        Site="$(echo $file | sed 's/.txt$//'| cut --d="/" -f 5)"
        echo -e "\e[1;33mFile Checked = $Site \
        uniq="$(grep uniqueID | cut -f3 -d" ")"
        echo -e "Uniq IDs are :\n$uniq\n"
        AUG="$(grep Price  | cut -f3 -d" ")"
        echo -e "AUG is :\n$AUG\n"
    done < "$file"
Output that i am getting is :

[~]$ ./
Site Checked = test1

Uniq Hw IDs are :

AUG is :

Site Checked = test2

Uniq Hw IDs are :

AUG is :

Can somebody please suggest how to move forward with this.

Thanks in Advance!

Your grep commands don't have any input. Get rid of the while loop an just pass $file to each grep.

I am with the previous post. Your while loop is pointless as you do nothing with the read line anyway.
