Based on the example, it looks like the lines you want are at the end of a blank-line-delimited record, so it would probably be easiest (and maybe even most reliable), if you read the file in "paragraph mode", and pop lines off the end of each record until you hit one that consists of just dashes. Something like this (updated to rearrange the conditions for the while loop, which could make it more reliable):
#!/usr/bin/perl use strict; use warnings; $/ = ""; # set input record separator to paragraph mode my $recid = 0; while (<DATA>) { my @lines = split /\n/; my @wanted = (); while ( @lines and $lines[-1] !~ /^-{10}/ ) { unshift @wanted, pop @lines; } if ( @wanted ) { unshift @wanted, sprintf( "Record # %d", ++$recid ); print join( "\n", @wanted ), "\n"; } } __DATA__ IFDI_PXJPB_ID MJ_IFDI_CJYSP_HYJP_ +C -------------------------------------------------- ------------------- +- CJYSP_MP + ---------------------------------------------------------------------- +---------- CJYSP_SUI_MP + ---------------------------------------------------------------------- +---------- CJYSP_ID CJYSP_ID_FJIP_CD + PFB -------------------------------------------------- ------------------- +- --- XXXXXX99954499999-99999999_94334633_SPJS_334 XXXX + KHYSSPFKBUPP MFKPBIFJS FF IFC + KHYSSPFKBUPP MFKPBIFJS FF, IFC + SKS_3449436933_36559337_994 IF + US + FJIP_IFKBJ_ID MJ_FJIP_CJYSP_HYJP_ +C -------------------------------------------------- ------------------- +- CJYSP_MP + ---------------------------------------------------------------------- +---------- CJYSP_SUI_MP + ---------------------------------------------------------------------- +---------- CJYSP_ID CJYSP_ID_FJIP_CD + PFB -------------------------------------------------- ------------------- +- --- SKSJCK39954494444-36559366_94334633_FJPX_994 XXXX + KKP MFIFCY F/P + KKP-MFIFCY F/P + SKS_3447994645_36559366_994 IF + US + FJIP_IFKBJ_ID MJ_FJIP_CJYSP_HYJP_ +C -------------------------------------------------- ------------------- +- CJYSP_MP + ---------------------------------------------------------------------- +---------- CJYSP_SUI_MP + ---------------------------------------------------------------------- +---------- CJYSP_ID CJYSP_ID_FJIP_CD + PFB -------------------------------------------------- ------------------- +- --- SKSF43399543F9P49-36563753_94334633_FJPX_994 YBS + KDK PPC CYBP.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
