# Basic syntax:
FILELINES=`cat your_file.txt`
# Example usage:
# Say you have a file "your_file.txt" containing the following sample names
# and you want to iterate over them in a bash script:
SAMPLE1
SAMPLE2
SAMPLE3
# The bash script would look like:
SAMPLES=`cat your_file.txt`
for SAMPLE in $SAMPLES; do
echo $SAMPLE
done
