Get More Out of Google Chrome

The browser wars are heating up again. Microsoft's touting the improved performance and security of Internet Explorer 8 , dozens of new Firefox extensions are released every day, and, according to Apple, Safari 4 will be even faster than its speedy predecessor. Meanwhile, Opera just keeps chugging along at version 9.64, with version 10 beta 3 now available. Just a few weeks ago, Google announced its plans to create an operating system based on Chrome . Considering that the browser itself is barely a year old, such plans may be premature. Then again, maybe not. But for right now, I'll keep looking for ways to make the Chrome browser more useful. Last June, I described ways to change Chrome's default settings . Here's a look at ways to revamp the browser's interface and access some of its useful hidden features. Themes perk up Chrome's drab interface Google is famous for its no-frills look, which describes the default Chrome interface as well. You can spiff th

Split and Join Large Files

Just use the default GNU tools tar, split and cat. There is absolutely no need for any fancy gui tools or software that you have to run in Wine! Just type the following in a console window: tar cvzf - filename.iso | split -d -b 700m - filename.iso.tar.gz . This wil produce the following files: filename.iso.tar.gz.1 filename.iso.tar.gz.2 filename.iso.tar.gz.3 ... Burn to CD with your favorite burner, one file per disk. Then later if you want to restore the iso, first copy all the parts in one directory, and then type cat filename.iso.tar.gz.* | tar xvzf - That will give you back your original ISO. I needed this a few days ago for a >10G backup that I wanted to put on a FAT32 external drive (maximum file size: 2G). Worked like a charm! If you are concerned with space, replace the 'z' option in tar with 'j', and replace 'gz' in the filenames with 'bz2'. Bz2 compression is usually a bit better than gz compression, but it's slower. And if you really wa

Finding Files On The Command Line

One of the things I like about Linux is the command line. I have used nautilus, gnome-commander, konqueror, kommander, dolphin and thunar to manage files in Linux and these file managers are great for what they do. But there are times when one simply wants to find a file when working on the command line without having to open a GUI application. From the find man page: GNU find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence until the outcome is known at which point find moves on to the next file name. Find empty directories: find /path -depth -type d -empty Find empty files: find /path -depth -type f -empty Find a file with a specific name: find /path -name name_of_file Find a files with specific extensions: find /path -name "*.given_extension" Find files with specific permissions which have a ".txt. file extension: find /path -name '*.txt' -perm 644 Find files
