Using csh / awk / sed to compare database sizes in a txt file
Hello,


I have an output file showing database sizes across the 3 environments that I use (LIVE, TEST & DEVELOPMENT).

I am trying to write a script that lets me know if the size of a db on one environment is different to its corresponding db on the other environments.

Here is an example of the file......(Name Size Environment)

Code:
stevie_db 13000   LIVE
stevie_db 13000   TEST
stevie_db 14000   DEVELOPMENT
john_db   25000   LIVE
john_db   25000   TEST
john_db   25000   DEVELOPMENT




I want to compare database sizes & flag up any databases that are a different size in any of the environments. So in the above example, the database stevie_db will be flagged up (because it is a different size in DEVELOPMENT). Maybe we could append an asterisk to any line that matches our criteria, to show it is different.


I imagine the general syntax would be something along the lines of
If $1 on line 1 = $1 on any other line

Compare $2 on lines 1 and the matching line, flag up an error if they are different sizes.

Move on to Line 2 (and so on).


Is this something that could be done in awk?


Any help would be really appreciated.

Cheers,
Stevie

mdbfontencoding

mdbFontEncoding(5)						 The m17n Library						mdbFontEncoding(5)

NAME

       mdbFontEncoding - Font Encoding

DESCRIPTION

       The m17n library loads information about the encoding of each font form the m17n database by the tags <font, encoding>. The data is loaded
       as a plist of this format.

       FONT-ENCODING ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ENCODING [ REPERTORY ] ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ENCODING ::= SYMBOL

       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.

       For instance, this FONT-SPEC:

	   (nil alice0 lao iso8859-1)

       should be applied to all fonts whose family name is 'alice0 lao', and registry is 'iso8859-1'.

       ENCODING is a symbol representing a charset. A font matching FONT-SPEC supports all characters of the charset, and a character code is
       mapped to the corresponding glyph code of the font by this charset.

       REPERTORY is a symbol representing a charset or 'nil'. Omitting it is the same as specifying ENCODING as REPERTORY. If it is not 'nil', the
       charset specifies the repertory of the font, i.e, which character it supports. Otherwise, whether a specific character is supported by the
       font or not is asked to each font driver.

       For so called Unicode fonts (registry is 'iso10646-1'), it is recommended to specify 'nil' as REPERTORY because such fonts usually supports
       only a subset of Unicode characters.
