I always tell others even though the Linux shell looks very backwards (thinking Ms-Dos 6.11 anyone?), experienced users can do much more in shorter time with their keyboards than others with their mouse with even the most most advanced graphical applications.
Take for example I would like to resize a folder of photos to half its resolution so I can upload it on the net. I only need issue a command
mogrify -resize 50% *.jpg
while it takes more a few more clicks on some useful software like IfranView on Windows for example (Using its batch convert feature. Which other software can you think of which does that?).
Visit ImageMagick’s site on using more of mogrify features or issue mogrify -help.
>thinking Ms-Dos 6.11 anyone?
You are kidding, right? Even the weakest shell is light years ahead of every DOS version microsoft dared to produce…
The usual laymen wouldn’t know what’s a shell, many I know would think that’s DOS.
