comment How can I fix incorrect mp3 duration?
ffmpeg with concat and -acodec copy does not re-encode - it just copies the streams (so it's fast), but creates a proper file in the first place (without useless header & tag data appearing multiple times in the resulting files).

cat is less than ideal for tasks like combining mp3s. A better way: http://superuser.com/questions/314239/how-to-join-merge-many-mp3-files

comment The “man” pages are not very well laid out or even helpful at times, alternatives?
Oh and if you write a realman utility, I propose you call it layman - real men (and women of course) use man :D

comment The “man” pages are not very well laid out or even helpful at times, alternatives?
The keywords are stated in mans manpage: ...on-line reference manual.... Manpages are not meant to be a tutorial, but a reference of all capabilities. Yes, it can be quite overwhelming (man gcc anyone?), but it is an invaluable comprehensive ressource that is easily accessible, no matter if you're connected to the internet or not. I agree however that many manpages lack useful examples (the manpage of find is an exception that comes to my mind).

comment trying to use sshfs on ubuntu
The mount point must be writeable by the user and empty. For the sake of testing, create a new mount point mkdir ~/mnttest and run sshfs -o sshfs_debug -p 22 root@10.14.5.182:/ ~/mnttest

comment trying to use sshfs on ubuntu
Can you really write to the mountpoint? Could you try it? What's the output of ls -ld /home/cp/Documents/cadev01 (or whatever mount point you're using now...)?

comment Why does ls -l output a different size from ls -s?
Metadata about files is stored in inodes. Each file system has a limited amount of inodes it can use. To see how many free inodes a file system has and the size of them: sudo tune2fs -l /dev/sdaX|grep Inode, or df -i for all partitions.

comment Problem using avconv to convert .mp4 to .webm
Just to be nitpicking: You should use the original avi source for the conversion to webm for maximum quality.

comment how to avoid space in filename?
Note that ffmpeg chooses the output container format depending on the extension. If you want another extension, you have to specify the container format - in this case with -f mpeg.

comment How to merge text files?
Yes, you're right of course. I'm just not sure about the sord order using cat *.txt. The for loop should be sorted.

comment Remove files of certain type, retain directory tree
Using -delete instead of -exec rm {} \; is much better (you need to run it only once then). Besides, the {} should be quoted: "{}"

comment What are the best Python IDEs?
bpython is an even better version of the python command line interpreter (it has tab completion, inline help and syntax highlighting).
