Extact tar.gz files

Writing by on Thursday, 31 of July , 2008 at 9:59 am

Let’s say you have a tar.gz file. For example, apache-ant-1.6.1-bin.tar.gz

# Decompress the zip file
gzip -d apache-ant-1.6.1-bin.tar.gz
# Extract the ant files in verbose mode
tar -xvf apache-ant-1.6.1-bin.tar

Append “confirm” (without quotes) to the kernel line

Selectively Delete Firefox Saved Form Information

Writing by on Tuesday, 15 of July , 2008 at 11:51 pm

So you love the auto-complete feature but Firefox’s Clear Private Data deletes everything. But if you want to delete just selected entries (for example, if you had a typo in your login information etc. and want to delete just some selected entries) use the shortcut Shift+Del. On the page, click on the text field and let Firefox list appear. Use your arrow keys in the list of choices and navigate to the “bad” entry and hit Shift+Del. It will be removed.
