shell error messages not displayed as a message box!!!

why does linux display shell error messages like "dependency not found" in a message box in x???

in windows you would see always see a "dependency not found" message in a message box!!!

by the way, why are file names case-sensitive in the shell???

and why do you need to add "\" before every space in a file name with spaces???

I didn't know it did. Which distribution are you using?

It's a design decision: in Linux, you can have the same filename, once in uppercase, once in lowercase, and they will point to two different files.

Because parameters are separated by spaces. If you didn't put the backslash, your program would read the two halves of the filename as separate filenames, and hopefully not find them and throw up an error message. You've probably seen this in action...

You left out not between linux and display.
Because it's a terminal, not a X server window, and doesn't display graphics.

Not if you're working from command line, such as a DOS prompt.

Because Linux uses case sensitive file names - higher intelligence. This allows
you to have more possibilities of filenames. I won't do the math for you, but
if you're interested enough you can calculate how many more with case
sensitive versus not case sensitive.

Because Linux doesn't use ambiguous spaces in filenames. Here's a script to remove
all the spaces from filenames and replace them with the _ of higher intelligence

Code:

 #!/bin/bash

IFS='

'

j=`find $1 -printf "%d\n" | sort -u | tail -n 1`

j=$((j-1))

echo "Max dir depth:" $j

for (( i=0; i<=j ; i++ ))

do

  for name in `find -mindepth $i -maxdepth $i -iname "* *" -printf "%p\n"`

  do

    newname=`echo "$name" | tr " " "_"`

    echo "$name" "$newname"

    mv "$name" "$newname"

  done

done

user222, this isn't M$windows. You don't have to pay tons of $ to get the kind of popup dialog you want. This is Linux; open sourse, not commercial development to someones pocketbook. If you want popups like that, and you have the programming skills to make it work, then do so and offer it back to the community. If you don't have the programming skills, but know someone who does, get them involved.
Basically, if you want window$ functionality, stay with window$. Linux is a work in process, still growing and improving. Search the boards; talk to people. Someone will hear your plea and will write the code.
Live long and prosper.
