Parsing file, reading each line to variable, evaluating date/time stamp of each line
So, the beginning of my script will cat & grep a file with the output directed to a new file. The data I have in this file needs to be parsed, read and evaluated.
Basically, I need to identify the latest date/time stamp and then calculate whether or not it is within 15 minutes of the current date/time at run time.
My logic:
-read each line into an array using a while loop
-create a variable for each date/time stamp per line
-compare the date/time stamp from one line to the next to determine the most recent
-keep evaluating dat/time stamps until EOF
-once most recent date/time stamp has been identified, check to see that it is within 15 minutes of current date/time
- print message to screen "check complete, time is within 15 minutes" .. OR .. "check failed, time exceeds 15 minutes"
here is the test data set:
I appreciate any help that can be provided. I am new to Unix and have only done some light coding in C+ and Java ... VERY light coding at that.
I have to capture the creation date and time stamp for a file. The ls command doesn't list all the required information. I need year, month, day, hour, minute and second.

Hi
I use "touch -t xxxxxxxx" command to set date/time stamp of a file. My requirement is to read the date/time stamp of a file and apply it to another file.
Is there anyway to do it simple instead of manually taking date/stamp of first file?
TIA

Hi All,
I have been using a program on windows called AutoKey.
My environment at work is Linux and I have been experimenting with expect. Very powerful. I can move my AutoKey scripts to Linux using Expect once I am educated on how to read from a file using Expect.

I need some help. I would like to read in a text file.
Take a variable such as ROW-D-01, compare it to what's in one line in the text file such as PROD/VM/ROW-D-01 and only input PROD/VM into a variable without the /ROW-D-01.
Is this possible? any help is appreciated. (2 Replies)
