File 1 has 6 lines in it:
Code:
Line 1 is /home/cmccabe/Desktop/validate/file1.txt found expected header
Line 2 is /home/cmccabe/Desktop/validate/file1.txt found expected order of fields
Line 3 is /home/cmccabe/Desktop/validate/file1.txt R_Index is a number
Line 4 is/home/cmccabe/Desktop/validate/file1.txt PopFreqMax is valid
Line 5 is /home/cmccabe/Desktop/validate/file1.txt Quality is a character
Line 6 is /home/cmccabe/Desktop/validate/file1.txt HGMD and Sanger are valid
 Line 1 matches the expected pattern in description so "LINE IS GOOD"
Line 2 matches the expected pattern in description so "LINE IS GOOD"
Line 3 matches the expected pattern in description so "LINE IS GOOD"
Line 4 matches the expected pattern in description so "LINE IS GOOD"
Line 5 matches the expected pattern in description so "LINE IS GOOD"
Line 6 matches the expected pattern in description so "LINE IS GOOD"

Since "LINE IS GOOD" = 6 then File1 is verified (desired output), but if the pattern is anything else then the "LINE IS GOOD" will be less than 6 so the File is not verified.
File 2 has 6 lines in it:
Code:
Line 1 is /home/cmccabe/Desktop/validate/file1.txt found expected header
Line 2 is /home/cmccabe/Desktop/validate/file1.txt found expected order of fields
Line 3 is /home/cmccabe/Desktop/validate/file1.txt R_Index is a number
Line 4 is/home/cmccabe/Desktop/validate/file1.txt PopFreqMax is valid
Line 5 is /home/cmccabe/Desktop/validate/file1.txt Quality is a character
Line 6 is /home/cmccabe/Desktop/validate/file1.txt HGMD and Sanger are valid
 Line 1 matches the expected pattern in description so "LINE IS GOOD"
Line 2 matches the expected pattern in description so "LINE IS GOOD"
Line 3 matches the expected pattern in description so "LINE IS GOOD"
Line 4 matches the expected pattern in description so "LINE IS GOOD"
Line 5 matches the expected pattern in description so "LINE IS GOOD"
Line 6 matches the expected pattern in description so "LINE IS GOOD"

Since "LINE IS GOOD" = 6 then File1 is verified (desired output), but if the pattern is anything else then the "LINE IS GOOD" will be less than 6 so the File is not verified.
File 3 has 6 lines in it:

Line 2 is /home/cmccabe/Desktop/validate/file1.txt found expected order of fields
Line 3 is /home/cmccabe/Desktop/validate/file1.txt R_Index is a number
Line 4 is/home/cmccabe/Desktop/validate/file1.txt PopFreqMax is valid
Line 5 is /home/cmccabe/Desktop/validate/file1.txt Quality is a character
Line 6 is /home/cmccabe/Desktop/validate/file1.txt HGMD and Sanger are valid
 Line 1 matches the expected pattern in description so "LINE IS GOOD"
Line 2 matches the expected pattern in description so "LINE IS GOOD"
Line 3 matches the expected pattern in description so "LINE IS GOOD"
Line 4 matches the expected pattern in description so "LINE IS GOOD"
Line 5 matches the expected pattern in description so "LINE IS GOOD"
Line 6 matches the expected pattern in description so "LINE IS GOOD"

Since "LINE IS GOOD" = 6 then File1 is verified (desired output), but if the pattern is anything else then the "LINE IS GOOD" will be less than 6 so the File is not verified.
desired output
Code:
/home/cmccabe/Desktop/validate/file1.txt is verified
/home/cmccabe/Desktop/validate/file2.txt is verified
/home/cmccabe/Desktop/validate/file3.txt is verified

It is also possible that there could only be 1 or two files, but there will always be 6 lines in each file. I use FILENAME to represent each file instead of hardcoding it in.

Does this help and thank you Smilie.
