it does not work at all now, cause it put cmd in bg before the read has been done... :S

Code:
> jobs
[3] +  Running                 while read n m ; do;remsh ${m%:} "ls -d /$n" &;done < text
[2] -  Running                 while read n m ; do;remsh ${m%:} "ls -d /$n" &;done < text
[1]    Running                 while read n m ; do;remsh ${m%:} "ls -d /$n" &;done < text

yes, they exists, and I've to use remsh, so no verbose mode possible.

arf... probably I've mistaped something the first time I execute my script, caus it works (not fine, cause it search everytime on everyserver everyline...)

so, this works (not fine):
Code:
for n in `awk -F: '{print $1}' text`; do
for m in `awk -F: '{print $2}' text`; do
remsh $n "ls -d /$m"
done
done

I prefer this one (works fine):
Code:
for n in `cat text`; do
ser = `echo $n | awk -F: '{print $1}'`
dir  = `echo $n | awk -F: '{print $2}'`
remsh $ser "ls -d /$dir"
done

thank you mirni (and I don't understand why your while doesn't work)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
