awk- reading input file twice
Hello,
I've been trying to come up with a solution for the following problem; I have an input file with two columns and I want to print as an output the first column without any changes but for the second column, I want to divide it by its last value. Example input:
1 9
2 10
3 11
4 12
5 13
6 14
Desired output:
1 9/14
2 10/14
3 11/14
4 12/14
5 13/14
6 14/14
So I don't really know how to read the file once in order to get the last value of the second column and then read it once again in order to print both columns, the second one divided by this last value.
Thank you for the help!

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.
