  • Retrieving a specific value from “df -h” using shell

    - by diegodias
    When I use df -h, I get the following output: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 59G 2.2G 54G 4% / /dev/sda1 122M 38M 78M 33% /boot tmpfs 1.1G 0 1.1G 0% /dev/shm 10.10.0.105:/somepath 11T 8.4T 2.1T 81% /storage4 10.11.0.101:/somepath 15T 8.9T 5.9T 61% /storage1 /dev/mapper/patha 5.0T 255G 4.8T 5% /storage5_vol0 /dev/mapper/pathb 5.0T 195G 4.9T 4% /storage5_vol1 /dev/mapper/pathc 5.0T 608G 4.5T 12% /storage5_vol2 I want to write a script that gets the value of Avail column on a specific storage. I used to use df -k /storage_name | tail -1 | awk '{print $3}' But the FileSystem column can have a value or not .. which would change the variable of my script from $3 to $4. How can I get the Avail on a single command line even if there are no values on the previous columns?

  • How to execute a shell script on startup?

    - by vijay.shad
    I have create a script to start a server(my first question). Now I want it to run on the system boot and start the defined server. What should I do to get this done? My findings tell me put this file in /etc/init.d location and it will execute when the system will boot. But I am not able to understand how the first argument on the startup will be start? Is this predefined somewhere to use start as $1? If I want to have a case startall that will start all the servers in the script, then what are the options I can manage. My Script is like this: #!/bin/bash case "$1" in start) start ;; stop) stop ;; restart) $0 stop $0 start ;; *) echo "usage: $0 (start|stop|restart)" ;; esac

  • Colorizing your terminal and shell environment?

    - by Stefan Lasiewski
    I spend most of my time working in Unix environments and using Terminal emulators. I try to use color on the commandline, because color makes the output more useful and intuitive. What are some good ways to add color to my terminal environment? What tricks do you do? What pitfals have you encountered? Unfortunately, support for color is wildly variable depending on terminal type, OS, TERM setting, utility, buggy implementations, etc. Here's what I do currently, after alot of experimentation: I tend to set 'TERM=xterm-color', which is supported on most hosts (but not all). I work on a number of different hosts, different OS versions, etc. I'm trying to keep things simple and generic, if possible. Many OSs set things like 'dircolors' and by default, and I don't want to modify this everywhere. So I try to stick with the defaults. Instead tweak my Terminal's color configuration. Use color for some unix commands (ls, grep, less, vim) and the Bash prompt. These commands seem to the standard "ANSI escape sequences" I've managed to find some settings which are widely supported, and which don't print gobbledygook characters in older environments (even FreeBSD4!) (For the most part). From my .bash_profile ### Color support # The Terminal application typically does 'export TERM=term=color' # Some terminal types will print Black, White & underlined with these settings. OS=`uname -s` case "$OS" in "SunOS" ) # Solaris9 ls doesn't allow color, so use special characters instead. LS_OPTS='-F' ;; "Linux" ) # GNU tools supports colors! See dircolors to customize colors export LS_OPTS='--color=auto' # Color support using 'less -R' alias less='less --RAW-CONTROL-CHARS' alias ls='ls ${LS_OPTS} export GREP_OPTIONS="--color=auto" ;; "Darwin"|"FreeBSD") # Most FreeBSD & Apple Darwin supports colors # LS_OPTS="-G" export CLICOLOR=true alias less='less --RAW-CONTROL-CHARS' export GREP_OPTIONS="--color=auto" ;; esac

  • Shell script to fix bad filenames? [closed]

    - by Ze'ev
    I'm IT at my small firm; and, despite my dire warnings, everyone puts files on the server with awful names, including leading & trailing spaces, bad characters (including \ ; / + . < > - etc!) They do this by accessing the (FreeBSD/FreeNAS) server via AFP on Macs, so no part of the system complains. Is there a script I can use to go through an entire directory tree and fix bad filenames? Basically replace all spaces & bad ASCII with _ ... and if a file already exists, just slap a _2 or something on the end. I don't suppose there's a way to get the system to enforce good filenaming conventions, is there?

  • Shell script to block proftp failled attempt

    - by Saif
    Hello, I want to filter and block failed attempt to access my proftp server. Here is an example line from the /var/log/secure file: Jan 2 18:38:25 server1 proftpd[17847]: spy1.XYZ.com (93.218.93.95[93.218.93.95]) - Maximum login attempts (3) exceeded There are several lines like this. I would like to block any attempts like this from any IP twice. Here's a script I'm trying to run to block those IPs. tail -1000 /var/log/secure | awk '/proftpd/ && /Maximum login/ { if (/attempts/) try[$7]++; else try[$11]++; } END { for (h in try) if (try[h] > 4) print h; }' | while read ip do /sbin/iptables -L -n | grep $ip > /dev/null if [ $? -eq 0 ] ; then # echo "already denied ip: [$ip]" ; true else logger -p authpriv.notice "*** Blocking ProFTPD attempt from: $ip" /sbin/iptables -I INPUT -s $ip -j DROP fi done how can I select the IP with "awk". with the current script it's selecting "(93.218.93.95[93.218.93.95])" this line completely. But i only want to select the IP.

  • "Bootstrap" python script in the Windows shell without .py / .pyw associations

    - by PabloG
    Sometimes (in customer's PCs) I need a python script to execute in the Windows shell like a .CMD or .BAT, but without having the .py or .pyw extensions associated with PYTHON / PYTHONW. I came out with a pair of 'quick'n dirty' solutions: 1) """ e:\devtool\python\python.exe %0 :: or %PYTHONPATH%\python.exe goto eof: """ # Python test print "[works, but shows shell errors]" 2) @echo off for /f "skip=4 delims=xxx" %%l in (%0) do @echo %%l | e:\devtools\python\python.exe goto :eof ::---------- # Python test print "[works better, but is somewhat messy]" Do you know a better solution? (ie: more concise or elegant)

  • Which book for windows Shell programming?

    - by serefarikan
    I've been looking for a good book for windows shell programming, and the only one I could find is Visual C++ Windows Shell Programming by Dino Eposito: http://www.wintellect.com/BookInformation.aspx?ASIN=1861001843 It is an old book, and I'd like to know if you know of any good resources which could help. I need to develop a couple of windows explorer extensions, and apparently managed code is not recommended by Microsoft at least for some of these tasks. So I'm searching for a good resource for native development. Kind regards Seref

Perhaps there is a better way of generating such a a log?
