in reply to Get home dir from shell

since it considers $HOME as a variable
Which is why you escape it: perl -e 'print `echo \$HOME`'

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

    It will print $HOME
      moo@cow>perl -e 'print `echo \$HOME`' /home/moo
      ~$ perl -e 'print `echo $HOME`' ~$ perl -e 'print `echo \$HOME`' /home/kennethk ~$ perl -e 'print `echo \\$HOME`' \ ~$ perl -e 'print `echo \\\$HOME`' $HOME ~$ perl -e '$q = chr 39; print `echo $q\$HOME$q`' $HOME ~$ perl -e '$loc = q{\$HOME}; print `echo $loc`' $HOME
      Try outputting your command to make sure it's what you think it is.

        Two more:

        c:\>perl -e "print `echo \%HOME\%` " c:\brocmi c:\>perl -e "print `echo %HOME%` " crocmi
