    Handy bash commands for finding out stuff in Linux

    # Find CPU specifications
    cat /proc/cpuinfo
    # What pci cards are installed and what irq/port is used
    cat /proc/pci
    # Memory information
    free
    # How is the hard drive partitioned
    fdisk /dev/hdXX -l
    # How much free drive space
    df -h
    # Find running kernel version
    uname -r
    # Find X server version
    X -showconfig
    # What is the distribution
    cat /etc/.product
    cat /etc/.issue
    cat /etc/issue
    cat /etc/issue.net
    sysinfo
    # For finding or locating files
    find
    locate
    which
    whereis
    Look at man <command> or info <command> for the flags and options you can use for bash commands.

    What have I overlooked? Add your essential informational bash commands/scripts.

    Or run GKrellm and over half of these will be displayed at all times

    But gkrellm displays a graphical representation without a lot of specifics.

    Then there is gtop, ktop, etc.

    I was specific about the command line in the subject as all distros (Mandrake users, double check me) use bash..

    du

    (show disk usage by current directory and all subdirectories) is one of my favorites. Handy for figuring out if it's time to make a backup CD yet

    Good one. Possibly better if piped to less

    du | less

    or re-directed to a file

    du > diskusage

    GKrellm isn't just a graphical tool...you can configure it to show you the hard numbers also. It's just an option, did I sound negetive at all? I don't think so, There are lots of good suggestions in this thread and the more the better. I use GKrellm for a general view. If I need more detail these are the commands to use.

    Cool

    Yep Mandy does use bash.

    Two of my faves:

    dmesg|less
    to find out what went wrong at boot-up

    ps -A
    to see what's running

    1) Find a process id by name
    ps -ef |grep -i <plain text>

    For example, XCDroast

    ps -ef |grep -i xcdroast /* Case Insensitive */

    2) See current environment list, or pipe to file
    env |more
    env > environmentvariablelist.txt

    3) Show current userid and assigned groups

    id

    4) Scan for problems with system, executing a file, etc

    tail -f /var/log/message

    5) See all command aliases for the current user
    alias

    6) rpms installed on current system
    rpmquery --all |more
    rpmquery --all > filenameyouwouldlike.txt
    rpmquery --all | grep -i <plaintext> /* find specific rpms with name in them */

    Hmm. I did not know that. I just use it as a small monitor to check cpu and modem. I guess I'll have to read the man page since the nice, kind moderator had a minor mental slip and did not mention the command line options or the config file needed for those nice features.
    did I sound negetive at all?
    Not really, I just thought you needed some knocking around just to see if you respond like mdwatts.

    Even though threadhead thinks it's too much like insert tip here?????

    I found these pretty cool.

    top -q -d 2 , shows top resource hoggers, refreshes every 2 seconds. top -n 1 -b > <filename> (pipes all enviroment variables to filename.

    set | less , shows all enviroment variables associated with a process.
