Help with Simple Perl/Python Script

I have the following problem, which I need done in Perl/ or Python using Unix/linux filters...

1. You have a very large file, named 'ColCheckMe', tab-delmited, that you are asked to process. You are told that each line in 'ColCheckMe' has 7 columns, and that the values in the 5th column are integers.
Using Perl/python (and standard LINUX/UNIX filters), indicate how you would verify that these conditions were satisfied in 'ColCheckMe'


2. In the same file, you are told that each value in column 1 is unique. How would you verify that?


3. Write a shell function that counts the number of occurrences of the word “SpecStr” in the file 'ColCheckMe'.


Thanks a lot

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME
mdbFontSize - Font Size DESCRIPTION
In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format. FONT-SIZE-ADJUSTMENT ::= PER-FONT * PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')' FONT-SPEC ::= '(' [ FOUNDRY FAMILY [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]] REGISTRY ')' ADJUST-RATIO ::= INTEGER FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font. See m17nFont for the meaning of each property. ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT: ((devanagari-cdac) 150) instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is 'devanagari-cdac'.
