UNIX for Dummies Questions & Answers

Hi everyone!

I need to compare two file sizes.

One of them (size) will be stored in a flat file and the other coming from a listed file.

I can now get the first file size using:

Code:

 
SIZE=`ls -l $DOCTYPE | awk '{print $5}'`

1. How can I store this value in a flat file?
2. How can I read the flat file value in order to compare with a new file?
2.1 Could you please include the string-to-long conversion?

For question 1, I tried:

Code:

sed -n "${SIZE}" file > temp_size

but my created file is empty.

Sorry about this question, but this is my very first script.

Thank you all!

Code:

ls -l $DOCTYPE | awk '{print $5}' >myfile

will store the result in the file called myfile

Code:

temp_size=`cat myfile`

will load the value into variable temp_size

Don't understand your third question.

no temp file generated.

Code:

file1=abc
file2=xyz

diff <(ls -l $file1| awk '{print $5}') <(ls -l $file2| awk '{print $5}')
