EOL ($) simple regexp in tcsh vs bash
I found the answer (I think).

It is in the tcsh man page.

Code:

sed "s/$/blah/g" filename

If you use double quotes (") this won't work. The dollar sign ($) will be interpreted as a variable. You'll get "Illegal variable."

But if you use single quotes...

Code:

sed 's/$/blah/g'

This works.

Now how do you deal with substituting a single quote characater?

Code:

sed 's/$/\'/g' filename
sed "s/$/\'/g" filename

Neither works. (Using FreeBSD, console or xterm.)

I'm reading the tcsh man page now... hoping to find the answer.

Update: I read some writings on the internet. The grymoire site says mixed quoting is a problem. Seems like, based on other stuff I've read, csh/tcsh makes it difficult to use the many UNIX utilities (i.e. script them), but may make it easier to call C functions of the OS, from the command line?

And ksh was an attempt to blend the two uses of the shell: UNIX utilities and UNIX C functions? The later I suspect is a rarer use?

logprof.conf

LOGPROF.CONF(5) 						     AppArmor							   LOGPROF.CONF(5)

NAME

       logprof.conf - configuration file for expert options that modify the behavior of the AppArmor logprof(1) program.

DESCRIPTION

       The logprof(1) program can be configured to have certain default behavior by the contents of logprof.conf.

       The [qualifiers] section lists specific programs that should have a subset of the full ix/px/ux list when asking what mode to execute it
       using.

       Since creating a separate profile for /bin/bash is dangerous, we can specify that for /bin/bash, only (I)nherit, (U)nconstrained, and
       (D)eny should be allowed options and only those will show up in the prompt when we're asking about adding that to a profile.

       Likewise, if someone currently exec's /bin/mount in ix or px mode, things won't work, so we can provide only (U)nconstrained and (D)eny as
       options.

       And certain apps like grep, awk, sed, cp, and mkdir should always inherit the parent profile rather than having their own profile or
       running unconfined, so for them we can specify that only (I)nherit and (D)eny are the allowed options.

       Any programs that are not listed in the qualifiers section get the full (I)nherit / (P)rofile / (U)nconstrained / (D)eny option set.

       If the user is doing something tricky and wants different behavior, they can tweak or remove the corresponding line in the conf file.

       The [defaulthat] section lists changehat-aware programs and what hat logprof(1) will collapse the entries to for that program if the user
       specifies that the access should be allowed, but should not have it's own hat.

       The [globs] section allows modification of the logprof rule engine with respect to globbing suggestions that the user will be prompted
       with.

       The format of each line is-- "<perl glob> = <apparmor glob>".

       When logprof(1) asks about a specific path, if the perl glob matches the path, it replaces the part of the path that matched with the
       corresponding apparmor glob and adds it to the list of globbing suggestions.

       Lines starting with # are comments and are ignored.

EXAMPLE

	 [qualifiers]
	   # things will very likely be painfully broken if bash has it's own profile
	   /bin/bash  = iu

	   # mount doesn't work if it's confined
	   /bin/mount = u

	   # these helper utilities should inherit the parent profile and
	   # shouldn't have their own profiles
	   /bin/awk   = i
	   /bin/grep  = i
	   /bin/sed   = i

	 [defaulthat]
	   /usr/sbin/sshd	    = EXEC
	   /usr/sbin/httpd2	    = DEFAULT_URI
	   /usr/sbin/httpd2-prefork = DEFAULT_URI

	 [globs]
	   # /foo/bar/lib/libbaz.so -> /foo/bar/lib/lib*
	   /lib/lib[^/]+so[^/]*$  = /lib/lib*so*

	   # strip kernel version numbers from kernel module accesses
	   ^/lib/modules/[^/]+/   = /lib/modules/*/

	   # strip pid numbers from /proc accesses
	   ^/proc/d+/		    = /proc/*/
