Check if *hardware* is 32bit or 64bit

This command tell you if your hardware is 32 or 64 bits even if you install a 32bits OS on a 64 bits hardware.

If your distro don't support the -q switch, try doing :

grep &>/dev/null '\<lm\>' /proc/cpuinfo && echo 64 bits || echo 32 bits

shows whether your CPU supports 64bit mode

it shows whether your CPU supports 64 bit (x86-64) mode. uname -a only shows whether you have 64 bit (x86-64) or 32bit (i386) OS installed, this one-liner answers question: Can I install 64bit OS on this machine?

How to find all open files by a process in Solaris 10

Executing pfiles will return a list of all descriptors utilized by the process

We are interested in the S_IFREG entries since they are pointing usually to files

In the line, there is the inode number of the file which we use in order to find the filename.

The only bad thing is that in order not to search from / you have to suspect where could possibly be the file.

Improvements more than welcome.

The letter your commands most often start with

Kind of fun if you're that was inclined. I figured most of my commands start with s. sudo, screen, ssh etc. This script tells me what else they start with.

ls -lhR

Lists everithing using -l "long listing format" wich includes the space used by the folder. Displays it in -h "human readable form" (i.e. 2.2G, 32K), and -R recurses subfolders.

grep -e using a regex, show lines containing the word "total" or a ":" at the end of the line (those with the name of the folder) only.
