Top Forums Shell Programming and Scripting Read Embedded Newline characters with read (builtin) in KSH93 Post 302487133 by DGPickett on Tuesday 11th of January 2011 01:56:56 PM

Well, how does the shell know which line feeds are real?

You might write a standard (local shared), postprocessing, sql tool (wrapper) for all to use, and make it encode embedded linefeeds in a printf friendly form, while escaping any printf metacharacters in the flow. It seems unlikely people will enter '\n' or '%' in their text, but with escapes, it would stay '\n' and '%'! It can trim and divert headers, counts, dividers and messages at the same time. It will be like JDBC/ODBC or ESQL, but crude and more work. Why not step up to a RDBMS tool or existing scripting extension for your RDBMS, sybperl or such?
