Hi all-
I have a variable that contains a web page:
echo $STUFF
<html> <head> <title>my page</title></head> <body> blah blah etc..
Can I use the shell's parameter expansion abilities to remove just the tags?
I thought that FIXHTML=${STUFF//<*>/} might do it, but it didn't seem to... (2 Replies)

Say you have this numeric variable that can be set by the user but you never want it to leave a certain range when it gets printed. How could you use parameter expansion such that it will never expand outside of that boundary? Thanks

gnunet-nat-server
GNUNET-NAT-SERVER(1) General Commands Manual GNUNET-NAT-SERVER(1)NAME
gnunet-nat-server - help GNUnet setup test network setup with NAT
SYNOPSIS
gnunet-nat-server [options] PORT
DESCRIPTION
Normal GNUnet end-users should not concern themselves with gnunet-nat-server. In fact, distributions are encouraged to consider not ship-
ping it at all. Running gnunet-nat-server's is similar to running hostlist servers: it is a special service to the community with special
requirements and no benefit to those running the service.
This program will listen on the specified PORT for incoming requests to test a peer's network connectivity. Incoming requests can ask it
to connect to a given IPv4 address (and port) using TCP or UDP and to send a 2-byte test message using the specified address. The program
can also be asked to send a "fake" ICMP response message to a given IPv4 address (for autonomous NAT traversal --- see the description in
the respective research paper).
The idea is that gnunet-nat-server will be run on some trusted hosts with unrestricted connectivity to allow GNUnet users to test their
network configuration. As written, the code allows any user on the Internet to cause the gnunet-nat-server to send 2-bytes of arbitrary
data to any TCP or UDP port at any address. We believe that this is generally harmless.
When running gnunet-nat-server, make sure to use a configuration that disables most NAT options but enables 'enable_nat_client' and sets
'internal_address' to the global IP address of your local host. Also, the gnunet-helper-nat-client should be installed locally and run
with root privileges (SUID), otherwise the gnunet-nat-server will not work properly.
Note that gnunet-nat-server could be run via gnunet-arm but typically is not. Also, the name of the host and port that gnunet-nat-server
is run on should be specified in the NATSERVER option in the [setup] section of the configuration file of hosts that are supposed to auto-
configure with this server.
OPTIONS -c FILENAME, --config=FILENAME
Use the configuration file FILENAME.
