I have a file called failedfiles.txt with the following content:
failed1
failed2
failed3
I need to use grep to return the content on each line in that file, and save the output in a list to be accessed. So I want something like this:
temp_list=$(grep "[a-z]" failedfiles.txt)
However, the problem with this is that when I type
echo ${temp_list[0]}
I get the following output:
failed1 failed2 failed3
But what I want is when I do:
echo ${temp_list[0]}
to print
failed1
and when I do:
echo ${temp_list[1]}
to print
failed2
Thanks.
You did not create an array. What you did was Command Substitution which would simply put the output of a command into a variable.
In order to create an array, say:
temp_list=( $(grep "[a-z]" failedfiles.txt) )
You might also want to refer to Guide on Arrays.
