I'm going to ignore most of your sample shell script for the moment because it doesn't seem to match any of your stated requirements. But, it is the only thing we have where you state what the explicit key words are that you are looking for in your text file. The key words your script defines are the literal strings: /Memsize/ $2, a literal single space character, /Real Time/ $2 , and /SASFoundation/ $3. Except for the second keyword in this (the single <space> character), I have not been able to find any of these key words in any of your sample files.

Searching through your sample input files for the data shown in your desired output above, I can find a line that would be matched by the ERE *real time * on a line that does NOT also contain the string seconds. Note that regular expressions and filename pattern matches are case-sensitive on UNIX and UNIX-like systems. Real Time and real time are NOT the same! Note that printing the value 6:00:00 from the input line:

Code:

      real time     6:00:00

(which does not contain the word seconds like other "real time" values:

Code:

      real time         0.06 seconds
      real time     3.01  seconds
      real time     0.3  seconds
      real time     3.0   seconds

under the heading SECONDS) is highly counterintuitive, and will NOT be displayed as you have requested using the printf format string %.1f. (Using that format with the input 6:00:00 would produce the output 6.0.) The string 6:00:00 seems to be hours, minutes, and second; not just seconds. And the test you're using to determine if a line should be printed is a string comparison; not a numeric comparison. With your test, a value of 51:00 (less than 1 hour) would compare greater than 5:00:00 and a value of 10:00:01 (more than 10 hours) would compare less than 5:00:00. Please provide a much clearer description of which lines containing real time should be reported and explain what should happen if more than one of those lines in a single input file are selected. (Your code would only the report the last selected line, if your code actually selected any lines matching this pattern. Is that what you want?)


The ERE MEMSIZE *= * seems to match the lines you are trying to grab from your input files:

Code:

MEMSIZE = 200;
MEMSIZE= 400;

The only line in any of your input files containing the string SASFoundation is:

Code:

z=/SAS/SAS94/SASFoundation/9.4;

which seems to have the key word z which is not mentioned anywhere in your description. Why is the value to be placed in your output under the heading SAXEXE file just the 3rd of the three or four directories named in the z key word's value?

The final field in your output is described in your explanation above as "the text filename that stores the information", and the MEMSIZE = 200; data in your output file comes from a file named SASFoundation_MEMSIZE.txt. But, the data for the last line of your sample output file comes from a file named more_than_5_hr.txt not from the file listed in your sample output: GT_5hr.txt.
