Question Need more info

While last line, always the 4th line? Always with a 34 in field 1?

When replace I with A, will data always be in this layout? Do we need to worry about other I characters on the line?

For instance, the following works, but perhaps not considering enough of what you need.

Code:
> head -3 file05 ; tail -1 file05 | sed "s/I/A/"
1|1|10|10|I|asdf|
2|1|10|10|I|sdfg|
4|1|10|10|I|hgfj|
34|0|10|10|A|sdg|

NAME
buildapp - application to create common lisp images SYNOPSIS
buildapp --output OUTPUT-FILE [--flag1 value1 ...] DESCRIPTION
Required flags: --output OUTPUT-FILE Use OUTPUT-FILE as the name of the executable to create Entry-point flags: --entry NAME Use the function identified by NAME as the executable's toplevel function. Called with SB-EXT:*POSIX-ARGV* as its only argument. If NAME has a colon, it is treated as a package separator, otherwise CL-USER is the implied package. --dispatched-entry DNAME Specify one possible entry function, depending on the name of the file that is used to start the application. The syntax of DNAME is APPLICATION-NAME/ENTRY-NAME. If the name used to start the executable matches APPLICATION-NAME, use ENTRY-NAME as the entry point. This can be used to choose one of many possible entry points by e.g. symlinking names to the application executable. If APPLICA- TION-NAME is empty, the specified ENTRY-NAME is used as a default if no other application names match. There may be any number of dispatched entry points, but only one default. Action flags: --load FILE Load FILE. CL:*PACKAGE* is bound to the CL-USER package before loading --load-system NAME Load an ASDF system identified by NAME --require NAME Use CL:REQUIRE to load NAME --eval CODE Use CL:EVAL to evaulate CODE. The code is read with CL:READ-FROM-STRING in the CL-USER package There may be any number of load/load-system/require/eval flags. Each is executed in command-line order before creating an executable. Load path flags: --load-path DIRECTORY When handling a --load, search DIRECTORY for files to load --asdf-path DIRECTORY When handling a --load-system, search DIRECTORY for ASDF system files to load --asdf-tree DIRECTORY When handling a --load-system, search DIRECTORY and all its subdirectories for ASDF system files to load There may be any number of load-path/asdf-path/asdf-tree flags. asdf-path arguments take precedence over asdf-tree arguments. Other flags: --help Show this usage message --logfile FILE Log compilation and load output to FILE --sbcl PATH-TO-SBCL Use PATH-TO-SBCL instead of the sbcl program found in your PATH environment variable For the latest documentation, see http://www.xach.com/lisp/buildapp/ buildapp 1.1 July 2010 BUILDAPP(1)
