Top Forums Shell Programming and Scripting Performance issue in UNIX while generating .dat file from large text file Post 302309268 by KRAMA on Tuesday 21st of April 2009 01:08:15 PM
Hi John,

The ksh version is 88f. Also i implemented the comand which you gave but the one having removing cut (i.e m_brch_cd=${d92_line:165:3} ) did not worked as you said it will work for ksh93 . And rest of the command did not improved the perfoprmance much . (it improved performance by 1-2 mins). Can you please help me with the suggestion of using AWK. I am very new to AWK .

OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
