Hi all, basicaly what i'm doing is writing a script that will check a environment variable periodically while running (looping)in the background (&) i need to be able to set/change this variable with any script
This example is not very useful as it stands, but we could let the application accept the data source name parameter from the command line as an option, or leave it empty and use theDBI_DSNenvironment variable. That makes the application much more flexible. 6.1.3. The Significance of Case...
[root@localhost DBI-1.636]# perl Makefile.PL *** Your LANG environment variable is set to 'zh_CN.UTF-8' *** This may cause problems for some perl installations. *** If you get test failures, please try again with LANG unset. *** If that then works, please email dbi-dev@perl.or...
Incorrect control of environment variables in PostgreSQL PL/Perl allows an unprivileged database user to change sensitive process environment variables (e.g. PATH). That often suffices to enable arbitrary code execution, even if the attacker lacks a database server operating system user. Versions be...
I think this is the suitable place to rise my question: I try to check if my gateway's IP matches with a defined value. For this, I catch the IP into a variable using qx() then I run an if statement: #!/usr/bin/perl $a = qx(ip ro ls | grep default | cut -d ' ' -f3...
If you want the old signal behaviour back regardless of possible memory corruption, set the environment variable "PERL_SIGNALS" to "unsafe" (a new feature since Perl 5.8.1). Using open() for IPC Perl's basic open() statement can also be used for unidirectional interprocess communication by ...
(1) $str =~ tr/aeiou/xxxxx/ We can put that into a test file which we can run to check which approach is the fastest, using a global $STR variable to assign to the "my $str" variable so as to avoid perl trying to optimize any of the work away by noticing it's assigned only...
In addition, theSYBASEenvironment variable should be set to the location of the FreeTDS installation. If usingbashorksh, the following commands can be used: export SYBASE=/usr/local/freetds Modify the application's source code. Minor changes will need to be made to the source code to allow ...
If the file is there but you still get the error, you should include the directory in which the file is located in the environment variableLD_LIBRARY_PATH(or the equivalent variable for your operating system). Under normal circumstances, Apache should have had the library path configured properl...
The PERL5OPT environment variable simulates me using those switches on the command line, and the PERL5LIB environment variable adds directories to the module search path. That way, I can change how Perl acts without changing the program. To add more options just as if I had specified them ...
