installing and building Go

Question

after installing go and setting the GOPATH value while trying to execute a file present in bin(hello.exe) as %GOPATH%\bin\hello,the error shows bash:fg: no such job(used gitbash)

Answer 1

The problem you're facing is due to the way you're referencing the GOPATH. In Bash (and every shell I've used), variables are accessed by preceding the variable name with a dollar ($) symbol, like so:

echo $GOPATH

so what you should be using to run your program is:

$GOPATH/bin/hello

(Note: in Bash paths are separated with forward slashes, rather than the back slashes used in Windows)

An explanation of the error message

In bash and other shells, the percentage (%) symbol is used to reference stopped jobs. For example, we could do:

vim

(vim opens)

pressing ctrl + z will then send a stop signal to vim and return you to the shell. typing jobs will then give you a list of stopped jobs:

jobs
[1]+  Stopped                 vim  (wd: ~)

you can then re-start the job, bringing it back to the foreground using

%1

or

fg %1

(one being the number of the stopped job),
