c linux ubuntu ksh
I’ve got a fairly well tested bit of an application I’m trying to get working on Ubuntu Linux, and having a lot of problems, seemingly with the ksh implementation. The problem seems to manifest when it is being called by the system build command.There is a ksh script which auto-generates a C header file from a C source file. When I try to run it via a system() call in a C application, the ksh crashes with a segfault.At the command line, I can run the command without problems, and it works corr

shell-script ksh error-handling
I am a database administrator working with DB2 on AIX. (Please continue to read as this is related more to ksh than DB2, otherwise I would have posted this over on dba.stackexchange.com.) I am attempting to write up ksh scripts for several of our database deployment as well as database maintenance scripts.I am in the process of putting error handling in our scripts to know whether or not something requires a hard fail or just a warning message, or can be ignored.With most AIX/ksh related tasks I

solaris ksh file-descriptors ulimit
I’m working on an old legacy application, and I commonly come across certain settings that no one around cam explain.Apparently at some point, some processes in the application were hitting the max number of files descriptors allowed per process, and the then team decided to increase the limit by adding the following to the init files of their shells (.kshrc):((nfd=16#$(/etc/sysdef | grep “file descriptor” | awk ‘{ print $1 }’ | cut -f3 -d “x”)))ulimit -n $nfdThis increases the output of ulimit

ksh
I have a program that crashes. I know it does, it’s supposed to in order to test some trap handling. The crash is expected behavior.When I run the program from ksh, the shell insists on printing helpful little messages like:./fpe.ksh: line 9: 105778: Floating exceptionHow do I make it stop that? I want the shell script to ignore the crash and keep going, without the error message.

linux shell unix ksh cat
I used the following command in my unix box.$ cat kshAnd it gave a rolling log of latin and greek letters and symbols and it kept on going with no signs of stopping. Eventually I had to close my connection tool to stop it.I was just wondering what was it displaying?

Our outsourced IT service provider runs the following script via cron to clean up Oracle core and trace files. It clearly is not a well-written script, but my question for the Serverfault crowd is whether there is an error or boundary condition that would have it remove other directories, such as these: /ora/admin/SCRM01P/bdump /ora/admin/SCRM01P/cdump /ora/admin/SCRM01P/pfile /ora/admin/SCRM01P/udumpWe recently had these directories deleted on a production system, crashing Oracle.

bash ksh error exit error-handling
Similarly to set -e performs an exit on “uncaught” $? != 0, I’d like to have this event trigger the execution of another command, e.g. a logger call. How can this be done?

shell ksh
As per my knowledge, to determine the current shell we use echo $0 in the shell. Rather I want my script to check in which shell it is running. So, I tried to print $0 in the script and it returns the name of the script as it should. So, my question is how can I find which shell is my script running in during runtime?

java unix jsp shell ksh
First and foremost I should acknowledge that I have no experience at all using Java ServerPages, but I’m positive about achieving this task if you guys help me out a bit since it doesn’t seem like something difficult for a seasoned JSP programmer.Anyway the thing is, there’s an actual running JSP application within a *NIX box which I somewhat administer with kind of good permissions. The idea is to create a new but dead simple JSP page to control some Korn Shell scripts I’ve got running there. S

ksh readonly typeset
I wish to source a script, print the value of a variable this script defines, and then have this value be assigned to a variable on the command line with command substitution wrapping the source/print commands. This works on ksh88 but not on ksh93 and I am wondering why.$ cat typeset_err.ksh #!/bin/ksh unset _typeset_var typeset -i -r _typeset_var=1 DIR=init # this is the variable I want to printWhen run on ksh88 (in this case, an AIX 6.1 box), the output is as follows:$ A=$(. ./typeset_err.ksh
