Read filenames from a text file and then make those files?

My code is given below. Echo works fine. But, the moment I redirect output of echo to touch, I get an error "no such file or directory". Why ? How do i fix it ? If I copy paste the output of only echo, then the file is created, but not with touch.

while read line           
do           
    #touch < echo -e "$correctFilePathAndName"
    echo -e "$correctFilePathAndName"           
done < $file.txt

If you have file names in each line of your input file file.txt then you don't need to do any loop. You can just do:

touch $(<file.txt)

to create all the files in one single touch command.

Ehm, lose the echo part... and use the correct variable name.

while read line; do
    touch "$line"
done < $file.txt

try :

echo -e "$correctFilePathAndName" | touch

EDIT : Sorry correct piping is :

echo -e "$correctFilePathAndName" | xargs touch

The '<' redirects via stdin whereas touch needs the filename as an argument. xargs transforms stdin in an argument for touch.

You need to provide the file name as argument and not via standard input. You can use command substitution via $(…) or `…`:

while read line
do
    touch "$(echo -e "$correctFilePathAndName")"
done < $file.txt
