Top Forums Shell Programming and Scripting Help with a script that involves processes Post 303015057 by Novia96 on Tuesday 27th of March 2018 05:16:00 AM

I just need to create a file with the list of active processes until the file himself his killed. The choises are made from a menu in another bash file. I'm not sure how to do it beacuse I'm new in shell scripting.

The output in file csv will be, for example:

(name of file: report_20170318_123027.csv)

user1;19;ps;12:23:25;0:00:03
user2;53;firefox;13:00:13;0:03:40
user3;99;vim;13:22:53;1:00:25
user1;130;firefox;12:00:24;3:00:41
...


In the .csv file every line in composed by: user;pid;command;start;cputime but I know how to cut every information to compose every line. The only thing i need is to know how can i copy active processes in a file named like this.

The difficulty for me is to understand the commands i must use to:
- copy the list of active processes in a file
- name the file with date and time like i explain before

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.11 30 Jan 2004 script(1)
