 Here is a quick tip on how to remove a list of files. Let's say you have the list of files inside a file called **files_to_remove**. Usually I would do something like this:
-`LIST=`cat files_to_remove``
+    LIST=\`cat files_to_remove\`
 and then
-`ls -al $LIST`
+    ls -al $LIST
 just to check what is in the list and if it looks good.
 
 And finally:
-`rm -vf $LIST`
+    rm -vf $LIST

 I got a package dependency issue when updating our 64-bit CentOS server, which was caused by two perl packages installed (i386 and x86_64).
-`
+```
 perl i386     4:5.8.8-32.el5_5.1     installed     28 M
 perl     x86_64   4:5.8.8-32.el5_5.1     installed     34 M
-`
+```
 I tried to remove it using rpm command but didn't work (maybe i just don't know the correct params with rpm).  My solution to remove package was using yum "_remove package_name.architecture_".   Ex:  `yum remove perl.i386`
 
 Any other shortcuts in deleting duplicate packages?

 Problem is I can't upload directory including sub-directories and files using command-line ftp.   I searched for similar problem and looks like you can't do this using command line ftp, unless you create a script.   One solution I found is the use of "[lftp](http://lftp.yar.ru/)".
 
-    \# lftp ftp_host
-    \> user ftp_user ftp_pass
-    \> mirror source target      (download entire directory tree)

 Usefull when transferring files between servers where you only have ftp access.
