Yes, sh's builtin "env" does this. > The env command does not show them. Only see things made by setenv command. It seems you're mixing shells here. The C Shell uses setenv to set variables, printenv to list them. The systems's sh uses export to set variables, and env to print them. Example (with exported and non-exported variable: $ export ASDF=yxcvbnm $ env | grep ASDF ASDF=yxcvbnm $ JKL=qwertzuiop $ env | grep JKL $ echo $JKL qwertzuiop And compare for the C shell: % setenv ASDF yxcvbnm % printenv | grep ASDF ASDF=yxcvbnm % set JKL=qwertzuiop % printenv | grep JKL % echo $JKL qwertzuiop If you omit the "| grep" step, the full list will be printed. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
