Can I use columns from text files in if statements?
Currently I am stuck on my program for my if statement, as I do not no how to get a specific collumn of text to check against my variable.

Code:
df -k /home/* > fd.txt
cat df.txt | tr -s " " | awk '{print $3, $4, $1}' > dfcap.txt

echo -n "Enter the size (in kilobytes) you wish to check against all user capacities: "
read cap

for i in df.txt
do
     if ($capacity -gt )
          echo [all used capacities above inputted variable]
     else
          echo [no one has a file usage above this size]
     fi
done

I know this is far from complete, but my main issue right now is that I do not know how to compare the variable against something else in a text file, and more specifically, a collumn in a text file. I'm trying to get it to check the first list in the second text file, but I can't seem to find anywhere how to do it
