As I read the source code of unix I wonder where u_ofile(it should be stdout) link to ?
Does it link to a file structure like ordinary files? :confused: (7 Replies)

Does anyone know how I can use gzip to zip a large log file on the fly.
My simulation is currently logging a large file that I need for analysis at a later point. However the files are so huge that I may even run out of disk space. The content is mainly text so when compressed the files are... (2 Replies)

Hi,
I have a program set to read in a text file, change certain characters and then print the altered version to the screen but does anyone know how to save the new version as another text file? And, if possible, how to specify the file name, and perhaps location?
Thanks! (2 Replies)
Today I used Terminal (invoked from Mac OS X 10.4.11) to view some data that is secured by a password.
After exiting Terminal, it occurred to me that a vestige of the data displayed on my screen might reside in memory or in disk file ... the actual file used for stdout, for example.
Do I need... (1 Reply)

ptree
ptree(1)ptree(1)NAME
ptree - print process trees
SYNOPSIS
/usr/bin/ptree [-a] [-c] [-z zone] [pid | user] ...
ptree prints the process trees containing the specified pids or users, with child processes indented from their respective parent pro-
cesses. An argument of all digits is taken to be a process-id, otherwise it is assumed to be a user login name. The default is all pro-
cesses.
The following options are supported:
-a All. Print all processes, including children of process 0.
-c Contracts. Print process contract memberships in addition to parent-child relationships. See process(4). This option
implies the -a option.
-z zone Zones. Print only processes in the specified zone. Each zone ID can be specified as either a zone name or a numerical zone
ID.
This option is only useful when executed in the global zone.
The following operands are supported:
pid Process-id or a list of process-ids. ptree also accepts /proc/nnn as a process-id, so the shell expansion /proc/* can be
used to specify all processes in the system.
user Username or list of usernames. Processes whose effective user IDs match those given are displayed.
Example 1: Using ptree
The following example prints the process tree (including children of process 0) for processes which match the command name ssh:
$ ptree -a `pgrep ssh`
1 /sbin/init
100909 /usr/lib/ssh/sshd
569150 /usr/lib/ssh/sshd
569157 /usr/lib/ssh/sshd
569159 -ksh
569171 bash
569173 /bin/ksh
569193 bash
The following exit values are returned:
0 Successful operation.
non-zero An error has occurred.
/proc/* process files
