Using programs to open files from within the script?
I am suppose to make a program that cuts the extension off of a file. It uses that .ext to decide which program needs to be used to open the file. This only finds the name of the program from a list of programs I made. My problem is when it has the name of the program it needs to use, how can I make the program open the file with code in the script.
It is okay to assume that files will only have one period.
I would like to have the commands or a scripts that will show me files that are not open by any process and meet a certain pattern (ie arch.log1_117512.dbf).
Basically I a wanting to delete all arched redo logs that oracle has popped out execpt for the current one it is writting to. I am... (3 Replies)

Hey guys,
Suppose i run passwd via bash shell. It is a suid program, which temporarily runs as root(owner) and modifies the user entries.
However, when i write a C file and give 4755 permission and root ownership to the 'a.out' file , it doesn't run as root in bash shell. I verified this by... (2 Replies)

pidof
PIDOF(8) Linux System Administrator's Manual PIDOF(8)NAME
pidof -- find the process ID of a running program.
SYNOPSIS
pidof [-s] [-c] [-n] [-x] [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] program [program..]
DESCRIPTION
Pidof finds the process id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems
used in run-level change scripts, especially when the system has a System-V like rc structure. In that case these scripts are located in
/etc/rc?.d, where ? is the runlevel. If the system has a start-stop-daemon (8) program that should be used instead.
OPTIONS -s Single shot - this instructs the program to only return one pid.
-c Only return process ids that are running with the same root directory. This option is ignored for non-root users, as they will be
unable to check the current root directory of processes they do not own.
-n Avoid stat(2) system function call on all binaries which are located on network based file systems like NFS. Instead of using this
option the the variable PIDOF_NETFS may be set and exported.
-x Scripts too - this causes the program to also return process id's of shells running the named scripts.
-o omitpid
Tells pidof to omit processes with that process id. The special pid %PPID can be used to name the parent process of the pidof pro-
gram, in other words the calling shell or shell script.
EXIT STATUS
0 At least one program was found with the requested name.
1 No program was found with the requested name.
NOTES
pidof is actually the same program as killall5; the program behaves according to the name under which it is called.
When pidof is invoked with a full pathname to the program it should find the pid of, it is reasonably safe. Otherwise it is possible that
it returns pids of running programs that happen to have the same name as the program you're after but are actually other programs. Note
that that the executable name of running processes is calculated with readlink(2), so symbolic links to executables will also match.
