+===== Local/remote webserver #2 (python) =====
+Serve files on port 8000 for anybody from the directory from where you start this command:
+python 2.x
+<code bash|>
+python -m SimpleHTTPServer
+</code>
+python 3.x
+<code bash|>
+python -m http.server
+</code>
+If other port is desired (for example 9000) then add port number to the command:
+<code bash|>
+python -m SimpleHTTPServer 9000

+===== Linux Get Hardware Serial Number From Command Line  =====

+===== Convert pdf to jpg =====
+  for file in `ls *.pdf`; do convert -verbose -colorspace RGB -resize 800 -interlace none \
+    -density 300 -quality 80 $file `echo $file | sed 's/\.pdf$/\.jpg/'`; done

+===== Find duplicate files in Linux =====
+Let’s say you have a folder with 5000 MP3 files you want to check for duplicates. Or a directory containing thousands of EPUB files, all with different names but you have a hunch some of them might be duplicates. You can cd your way in the console up to that particular folder and then do a
+<code>
+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=separate
+</code>
+This will output a list of files that are duplicates, according tot their HASH signature.
+Another way is to install fdupes and do a
+   fdupes -r ./folder > duplicates_list.txt
+The -r is for recursivity. Check the duplicates_list.txt afterwards in a text editor for a list of duplicate files.
+===== Linux - Top 10 CPU-hungry apps =====

+===== Find processes utilizing high memory in human readable format ======
+   ps -eo size,pid,user,command | sort -rn | head -5 | awk '{ hr[1024^2]="GB"; hr[1024]="MB"; for (x=1024^3; x>=1024; x/=1024) { if ($1>=x) { printf ("%-6.2f %s ", $1/x, hr[x]); break } } } { printf ("%-6s %-10s ", $2, $3) } { for ( x=4 ; x<=NF ; x++ ) { printf ("%s ",$x) } print ("\n") }'
