Problem iterating through PATH entries with spaces
I have a Bash script on Cygwin that tries to iterate through the directory entries in PATH. I need to convert the PATH value to a form that I can iterate through with "for var in $list; do".
For instance, an excerpt from my PATH value is this:
:/c/Program Files/Windows Imaging/:/c/Program Files/MySQL/MySQL Server 5.1/bin
I need to somehow coerce this into something I can iterate through, where each original PATH entry goes into a variable.
I tried replacing " " (space) with "\ " (escaped space). That seems correct, but I also have to replace ":" (colon) with " " (space). I also tried replacing ":" with "\n", but that doesn't seem to help. Inside the "for" loop, the value of "var" never includes the full directory name, it always breaks at spaces in the names.

Duh. Never mind. I discovered "IFS=$':'". Very simple.

filecap
FILECAP:(8) System Administration Utilities FILECAP:(8)
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

pscap(8), netcap(8), capabilities(7).
