1) Naming: does not matter, but popular choices are:
no extension (can rewrite later in any tool, like C or java)
.pl or .perl (tells people what it needs and that it is text)
2) Finding:
To use just entry name (my_perl_cmd), must be in $PATH (PATH=$PATH:/my_additional_bin_dir_path -- relative paths not recommended )
Else (declasse even when developing), must give a good, explicit relative or absolute path ( /my_additional_bin_dir_path/my_perl_cmd ).
3) Calling:
To be called without mentioning PERL, must be executable to you in file mode, and have the interpreter full path (/usr/bin/perl or whatever) and optionally one argument after #! on the first line.
Else (declasse even when developing), you can call perl directly and pass the script as a command line argument [ programfile ], which requires it has any necessary path and probably only be file mode readable to you. If perl is not in your PATH, it needs a relative or absolute path.
Hi all,
Not sure if this is the right forum to post query regarding perl script.
I have a perl script which internally calls a shell script. My problem is that the shell script should be passed command line arguments.
I call a shell script from perl using:
system("sript.sh");

Hi,
I just tried to call a simple script from a pretty simple C program. I could not succeed :-( a message was thrown saying
"sh: line 1: "Script name with path": Permission denied"
The C program and shell script are below, both are in the same directory and shell script is given... (7 Replies)
I need to write a c program that uses the fork and excel system calls to run the shell script mode invoked like this: "./mode 644 ls -l" (that is the argumetns will always be 644 ls -l)
here's the mode script:
#!/bin/sh
octal="$1"
shift
find . -maxdepth 1 -perm $octal -exec $@ {} \;

Hi,
I have a shell script which connects to a database and fetches the count of the records from a table. I want to embed this whole script in a C program. Also the count fetched should be available in the C program for further usage.
Please let me know how this can be done.
Thanks

Long story short: I'm working inside of a Unix SSH under a bash shell. I have to code a C program that generates a random number. Then I have to call the compiled C program with a Perl program to run the C program 20 times and put all the generated random #s into a text file, then print that text... (1 Reply)

platform::shell
platform::shell(n) Tcl Bundled Packages platform::shell(n)
__________________________________________________________________________________________________________________________________________________NAME
platform::shell - System identification support code and utilities
SYNOPSIS
package require platform::shell ?1.1.4?
platform::shell::generic shell
platform::shell::identify shell
platform::shell::platform shell
_________________________________________________________________DESCRIPTION
The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.
This package allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
requirement is that the other shell (identified by its path), is actually executable on the current machine.
While for most platform this means that the architecture of the interrogated shell is identical to the architecture of the running shell
this is not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.
For applications like a code repository it is important to identify the architecture of the shell which will actually run the installed
packages, versus the architecture of the shell running the repository software.
COMMANDS
platform::shell::identify shell
This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.
platform::shell::generic shell
This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.
platform::shell::platform shell
This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
KEYWORDS
operating system, cpu architecture, platform, architecture
