LKBEN11059: Howto do a command on every line in a textfile with bash and a do command


You need to do something for every line in a text file with whitespaces.




The solution from the knowledge base article 15 does not work when you have whitespaces in your file! This solution can loops over every line in the file 'allerrors.txt' and prints them on the screen. 

cat allerrors.txt |while read i;
do echo $i;
