Top Forums UNIX for Dummies Questions & Answers what is "not found?" Post 302200294 by zaxxon on Thursday 29th of May 2008 12:47:33 AM

Some people have a dot "." in their PATH variable like:

Code:
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:.

This would look in your current working directory - but for security reasons many leave it away, because if the dot is not placed at the end of the paths and for example someone puts a tool named "ls" in one of your usual working directories, but instead of the good old listing tool of the OS, it might be a program that does something bad to your system, it would be executed 1st instead of the real "ls", living at /usr/bin, because the 1st "ls" found in your paths will be executed. Ok?

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 5.10 30 Jan 2004 script(1)
