Splitting a String into an Array with a Custom Delimiter in a Bash Shell Script
Most high level languages have some sort of String.split([delimiter]) method to create an array of Strings tokenized by a user specified delimiter. This is a simple way to convert a CSV into an array.
Here is a quick way to do that in a bash shell script:
#!/bin/bash
SOURCE_STRING='foo|blah|moo'
# Save the initial Interal Field Separator
OIFS="$IFS"
# Set the IFS to a custom delimiter
IFS='|'
read -a TOKENS <<< "${SOURCE_STRING}"
for i in "${TOKENS[@]}"
do
echo "$i"
done
# Running VisualVM to Examine a JVM on a Remote Host Via an SSH Tunnel/Proxy Connection
VisualVM is a great tool for peering into a running JVM. In many cases, it won’t be one that is running on your local box.
The first thing to be done is to get jstatd running on the remote machine:
Create a security policy file on the remote machine (this assumes that you have an additional layer of security and that the outside world cannot access these ports and/or you have a VPN set-up and you are operating in that

At least under the FC 18 distro, there was no fancy GUI controls in the Advanced Settings for setting up an HTTP proxy over SSH for Chrome.
To get it all set up:
- Establish and ssh connection to the server to which you want to proxy:
- $ ssh -D localhost:1234 username@remote.server, where 1234 is the port number you want to use for the proxy
-
Run google-chrome from the command line passing it the proxy setting:
- $ google-chrome –proxy-server=socks5://localhost:1234
Screen Cheat Sheet
I have recently be introduced to the *nix screen command. Incredibly powerful tool for managing windows which mulitplexes a physical terminal between one or many processes. One of the uses it to maintain interactive shells on a remote server between remote connections to the machine.
It is enormously helpful when executing long running commands on remote servers. Especially those that timeout your ssh connection and or from machines that you are going to either disconnect from the net or shutdown.→ Continue reading “Screen Cheat Sheet”
Quick and Dirty HTTP Server to Transfer Files
If you need to stand up a quick HTTP Server to enable someone on your LAN to transfer some files use the following command in the directory that you want to ‘share’:
python -m SimpleHTTPServer
The default port is 8000, but you can run it as follows to specify a port
python -m SimpleHTTPServer 8080→ Continue reading “Quick and Dirty HTTP Server to Transfer Files”
Making the Switch to a Standing Desk
A few years back I had an office mate who used a standing desk. He said that he had been using a standing desk for many years and that once he got used to it he liked it much better. Since then, I have noticed a number of studies that indicate sitting for extended periods of time is just plain bad for you.
For a while I have been wanting to make the switch, and today I took the plunge.→ Continue reading “Making the Switch to a Standing Desk”
