Thread: 2 Small scripts

Im not sure if someone can help me but im trying to create a litte script that processes the output of the ls /dev command. For each value returned by this command the script must determine if a filename represents a character-special file, a block-special file, or neither.y brother says this is not possible but i dont think so can someone help me please ?

Hi,

at least bash can do it (please don't use ls).

see help test, test's file operators.

I've tried bash but i dont seem to be able to make it happen can someone perhaps let me know what to code?

Hi,
Try this

Code:

 ls -lh | grep ^whatever character you want 
               ls -lh | grep ^c(character)

Regards,
linpen.

Code:

for file in /dev/*
do test -b "$file" && type=block
   test -c "$file" && type=character
   if test -n "$type"
   then printf '%s is %s file\n' "$file" "$type"
        unset type
   fi
done

or something like

Code:

file /dev/* | grep '  *\(block\|character\)'

i apprecciate your help!
