in a script, WILL something like this work:

ORIG_PATH=$PATH
export PATH=/dir1/dir2:$PATH

RUN SOME JOBS .....

unset PATH
EXPORT PATH=$ORIG_PATH

There is no command called EXPORT; it is lowercase: export
Quote:

Also is there a way to not UNSET the path and look for particular dir and take it out from PATH variable??

There is (see http://cfaj.freeshell.org/shell/scripts/path-funcs-sh), but it is not necessary, since the change only affects the current script and its children.

NAME
filecap - a program to see capabilities SYNOPSIS
filecap [ -a | -d | /dir | /dir/file [cap1 cap2 ...] ] DESCRIPTION
filecap is a program that prints out a report of programs with file based capabilities. If a file is not in the report or there is no report at all, no capabilities were found. For expedience, the default is to check only the directories in the PATH environmental variable. If the -a command line option is given, then all directories will be checked. If a directory is passed, it will recursively check that directory. If a path to a file is given, it will only check that file. If the path to the file includes capabilities, then they are written to the file. OPTIONS
-a This tells the program to show all capabilities starting from the / directory. Normally the PATH environmental variable is used to show you capabilities on files you are likely to execute. -d This dumps all capabilities for reference. EXAMPLES
To check file capabilities in $PATH: filecap To check file capabilities of whole system: filecap -a To check file capabilities recursively in a directory: filecap /usr To check file capabilities of a specific program: filecap /bin/passwd To list all possible capabilities: filecap -d To set a file capability on a specific program: filecap /bin/ping net_raw net_admin SEE ALSO
