Rearrange pdf document coming from a simplex document feed scanner, feeded first with odd pages, then with even pages from the end. Needs pdftk >1.44 w/ shuffle. Similar to http://www.commandlinefu.com/commands/view/7965/pdf-simplex-to-duplex-merge where there are 2 separate documents, odd and even
0input=a.pdf ; pages=`pdftk $input dump_data | grep -i numberofpages | cut -d" " -f 2`; pdftk A=$input shuffle A1-$[$pages/2] A$pages-$[$pages/2+1] output "${input%.*}.rearranged.${input##*.}" -

Useful for big systems with lots of cards. (Update: does not work with USB disks)

In the field, I needed to script a process to scan a specific vendor devices in the network. With the help of nmap, I got all the devices of that particular vendor, and started a scripted netcat session to download configuration files from a tftp server. This is the nmap loop (part of the script). You can however, add another pipe with grep to filter the vendor/manufacturer devices only. If want to check the whole script, check in http://pastebin.com/ju7h4Xf4 Show Sample Output
0nmap -sP 10.0.0.0/8 | grep -v "Host" | tail -n +3 | tr '\n' ' ' | sed 's|Nmap|\nNmap|g' | grep "MAC Address" | cut -d " " -f5,8-15 -
You probably want to run `brew update` before you run this command Show Sample Output
1brew outdated | cut -f1 | xargs brew upgrade -
Useful for when you find the system runs out of file descriptors and you want to know why. Show Sample Output

Finds duplicates based on MD5 sum. Compares only files with the same size. Performance improvements on:
find -not -empty -type f -printf "%s\n" | sort -rn | uniq -d | xargs -I{} -n1 find -type f -size {}c -print0 | xargs -0 md5sum | sort | uniq -w32 --all-repeated=separateThe new version takes around 3 seconds where the old version took around 17 minutes. The bottle neck in the old command was the second find. It searches for the files with the specified file size. The new version keeps the file path and size from the beginning.1find -not -empty -type f -printf "%-30s'\t\"%h/%f\"\n" | sort -rn -t$'\t' | uniq -w30 -D | cut -f 2 -d $'\t' | xargs md5sum | sort | uniq -w32 --all-repeated=separate -
Gives the DNS listed IP for the host you're on... or replace `hostname` with any other host Show Sample Output
0host `hostname` | rev | cut -d' ' f1 | rev -
Its possible to user a simple regex to extract de username from the finger command. The final echo its optional, just for remove the initial space Show Sample Output
0finger $(whoami) | egrep -o 'Name: [a-zA-Z0-9 ]{1,}' | cut -d ':' -f 2 | xargs echo -
If you want to see your top ten cpu using processes from the browser (e.g. you don't want to ssh into your server all the time for checking system load) you can run this command and browse to the machines ip on port 8888. For example 192.168.0.100:8888 Show Sample Output
0while true; do ps aux | sort -rk 3,3 | head -n 11 | cut -c -120 | netcat -l -p 8888 2>&1 >/dev/null; done & -
Find the failed lines, reverse the output because I only see 3 indicators after the IP address, i.e. port, port#, ssh2 (in my file), cut to the 4th field (yes, you could awk '{print $4}'), reverse the output back to normal and then sort -u (for uniq, or sort | uniq). Show Sample Output
0grep Failed auth.log | rev | cut -d\ -f4 | rev | sort -u -
Outputs / monitors the content of the LOG_FILE , which matches the SEARCH_STR. The output is cutted by spaces (as delimiter) starting from column 7 till the end.
0tail -f LOG_FILE | grep --line-buffered SEARCH_STR | cut -d " " -f 7- -
1netstat -tn 2>/dev/null | grep :80 | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -nr | head

This will write to TAPE (LTO3-4 in my case) a backup of files/folders. Could be changed to write to DVD/Blueray. Go to the directory where you want to write the output files : cd /bklogs Enter a name in bkname="Backup1", enter folders/files in tobk="/home /var/www". It will create a tar and write it to the tape drive on /dev/nst0. In the process, it will 1) generate a sha512 sum of the tar to $bkname.sha512; so you can validate that your data is intact 2) generate a filelist of the content of the tar with filesize to $bkname.lst 3) buffer the tar file to prevent shoe-shining the tape (I use 4GB for lto3(80mb/sec), 8gb for lto4 (120mb/sec), 3Tb usb3 disks support those speed, else I use 3x2tb raidz. 4) show buffer in/out speed and used space in the buffer 5) show progress bar with time approximation using pv ADD : To eject the tape : ; sleep 75; mt-st -f /dev/nst0 rewoffl TODO: 1) When using old tapes, if the buffer is full and the drive slows down, it means the tape is old and would need to be replaced instead of wiping it and recycling it for an other backup. Logging where and when it slows down could provide good information on the wear of the tape. I don't know how to get that information from the mbuffer output and to trigger a "This tape slowed down X times at Y1gb, Y2gb, Y3gb down to Zmb/s for a total of 30sec. It would be wise to replace this tape next time you want to write to it." 2) Fix filesize approximation 3) Save all the output to $bkname.log with progress update being new lines. (any one have an idea?) 4) Support spanning on multiple tape. 5) Replace tar format with something else (dar?); looking at xar right now (https://code.google.com/p/xar/), xml metadata could contain per file checksum, compression algorithm (bzip2, xv, gzip), gnupg encryption, thumbnail, videopreview, image EXIF... But that's an other project. TIP: 1) You can specify the width of the progressbar of pv. If its longer than the terminal, line refresh will be written to new lines. That way you can see if there was speed slowdown during writing. 2) Remove the v in tar argument cvf to prevent listing all files added to the archive. 3) You can get tarsum (http://www.guyrutenberg.com/2009/04/29/tarsum-02-a-read-only-version-of-tarsum/) and add >(tarsum --checksum sha256 > $bkname_list.sha256) after the tee to generate checksums of individual files !
