# Description

The jshow command can be used to find jBASE files or programs. The command takes the general form:

jshow {Options} Name {Name ...}
1

Where:

  • Name is the Name of file, subroutine, program or dll/shared object,
  • Options can be:
Option Explanation
-a Display subroutine names in dll/shared object (Note that under UNIX, this must be the complete path to the shared object)
-c Display compile-time and source file
-d Display general information about the system {emulation | user | routine | binary | file}
-f File name only search
-h Display the help screen
-i Ignore case insensitivity and do a case sensitive search
-p Program name only search
-r Search using Regular Expression.
-s Subroutine,function, or method name only search.
-v Verbose mode

# Info

When performing a jshow -c on a program/subroutine you may see (DUP) as the display shows multiple occurrences. This is normal for non-subroutines (program) in that programs - when cataloged - produce a binary executable and a shared library (the latter is for efficiency when executing or running a the jshell).

However, you can also see (DUP) if the program/subroutine has been cataloged into multiple bin/lib directories. (See CATALOG)

# Note

jshow will now also display information on PROCs, PAragraphs and Nouns in the MD/VOC which meet the search criteria, i.e.:

jsh SandBox ~ -->jshow listu
Noun:                     /opt/jbase/SandBox/MD]D/listu (from MD/VOC )
Shared Object: (DUP!!)    /opt/jbase/CurrentVersion/bin/LISTU.so
Executable: (DUP!!)       /opt/jbase/CurrentVersion/bin/LISTU
Executable: (DUP!!)       /opt/jbase/CurrentVersion/bin/listu
Shared Object: (DUP!!)    /opt/jbase/CurrentVersion/bin/listu.so
