Top Forums Shell Programming and Scripting Replacing all occurences depending on parity Post 302364908 by Scott on Saturday 24th of October 2009 02:16:43 PM

Code:
awk -F'$' -v OFS="$" '{$2="latex " $2; $4="latex " $4} 1' file1  
Solve the equation $latex x^2=5$. Prove that $latex x$ is an irrational number.

If you have more than 4 $'s you can always do this in a for-loop:

Code:
awk -F'$' -v OFS='$' '{ for( I = 2; I <= NF; I+=2 )
  $I = "latex " $I
} 1' file1

Solve the equation $latex x^2=5$. Prove that $latex x$ is an irrational number.

NAME
rlatex -- Wrapper to run LaTeX/jadeTeX multiple times as needed SYNOPSIS
[env LATEXPRG=latex-binary ] rlatex [latex-document] Description rlatex applies LaTeX or another LaTeX-based macro package (most notably jadetex, pdflatex, or pdfjadetex) to a given document, as many suc- cessive times as needed. It checks the output of a LaTeX pass, and launches a new pass when it notices specific strings which notify that the document's processing has not been finished. Caveats This version is mostly tuned for jadetex, and may cause some problems when using pure LaTeX. This ought to be fixed some day. Copyright Copyright (C) 2001-2003 Alcove & Yann Dirson.
