bash export command

Question

I am encountering a strange problem with my 64bit Ubuntu - on the export command   Basically  I have got a VM installation on Ubuntu on my Win7  and I am trying to pass commands from my windows to my VM installation using a custom  given by client  software   So  on my VM  when I do   export foo bar echo  foo   everything works as expected   However  when I do the same through the custom software  which basically passes the linux command as a string to the bash shell   I get   export  command not found   I tried looking at the shell  using the custom software   using   echo  SHELL gt shell txt   and I get  bin bash which is expected and I still get the export  command not found error   I was wondering if anyone had seen this error before

export is a Bash builtin  echo is an executable in your  PATH  So export is interpreted by Bash as is  without spawning a new process   You need to get Bash to interpret your command  which you can pass as a string with the -c option   bash -c  export foo bar  echo   foo    ALSO   Each invocation of bash -c starts with a fresh environment  So something like   bash -c  export foo bar  bash -c  echo   foo    will not work  The second invocation does not remember foo   Instead  you need to chain commands separated by   in a single invocation of bash -c   bash -c  export foo bar  echo   foo

SHELL is an environment variable  and so it s not the most reliable for what you re trying to figure out  If your tool is using a shell which doesn t set it  it will retain its old value   Use ps to figure out what s really going on
