How can I echo the passwd file and redirect into a file, where all of the users are on the 1st line of the file, separated by spaces?

Im stuck

Hi:

# perl -naF":" -e 'push(@a,$F[0]);END{print "@a\n"}' /etc/passwd > myfile

Or, using awk:

awk -F: '{printf("%s ",$1)}END{print}' < /etc/passwd > myfile

cat /etc/passwd | awk -F: '{print $1}' | tr "\n" " "

echo $(awk -F: '{print $1}' /etc/passwd) > myfile

>Tingli: cat /etc/passwd | awk -

No need to use cat(1) here.
