      var r []byte
      if r, err = sh.Command("echo", "$PATH").Output(); err != nil {
        fmt.Println("filesystem anomalies")
        return
      }

它将直接输出 $PATH，理想状态下还是希望能够回馈环境变量列表

It is possible to redirect output?

Like: mysqldump dbname | gzip -9 > dump.sql.gz
Or stderr: tar czf archive.tar.gz ./dir/ 2> /tmp/error.log

It is possible to get the stdoutPipe?
just as func (c *Cmd) StdoutPipe() (io.ReadCloser, error)
if so, we can get the output when we exec the commands

Can we do something like this with the following with this plugin

$ > myshell
myshell > mycommand1 
myshell > mycommand2 some_sub_command --a some_args
myshell > exit
$ > 

Essentially have a shell that has it's own commands?

hi, if command like this, how to write?

nohup ~/dev/golang/myApps/src/gin_sample/gin_sample > /dev/null 2>&1&

my code works fine on foreignground, but can't run as daemon mode

package main

import (
    "github.com/codeskyblue/go-sh"
    "os"
    "syscall"
)

func main() {

    session := sh.NewSession()

    session.Command("nohup", "/Users/mmc/dev/golang/myApps/src/gin_sample/gin_sample")

    session.Stdout = os.NewFile(uintptr(syscall.Stdout), "/dev/null")
    session.Stderr = os.NewFile(uintptr(syscall.Stdout), "/dev/null")

    session.ShowCMD = true
    session.Run()
}

how to run in background?
thank you very much!

Is it possible to execute a shell script as part of other commands with this library?

-Thanks.

Hello!
I have question.
I have this code:

session := sh.NewSession()
    session.SetTimeout(time.Second * 30)
    session.ShowCMD = true
    session.SetDir(repositoryPath)
    session.Command(
        "rm", "-f", archiveFile, "&&",
        "git", "archive", branchName, "--format", "tar", "--output", archiveFile,
    )

And debug message:
[golang-sh]$ rm -f /tmp/archive.tar && git archive origin/master --format tar --output /tmp/archive.tar
But second command not executed...
If i remove "rm", "-f", archiveFile, "&&",
Its work, but i need this "&&" operator.
What mistake?

I'm trying to figure out, is it possible to work with interactive shell commands?

e.g. as a first step, connect to mongodb:
mongo --quiet --host=localhost blog

then perform arbitrary number of commands, like
db.getCollection('posts').find({status:'INACTIVE'})

and then
exit

UPD
figured it out

go-sh包 ，用到DOCKER操作指令时是无信息返回的。
觉得非常奇怪。
go-sh包所在程序在宿主机上运行，运行docker --help是可以正常获得反馈，
但是使用docker ps -a之类的指令时，是无反馈回来的，
而在cmd面板ssh操作是可以正常反馈的。
是跨容器导致了这个问题吗，有办法解决吗？很头大

diff <(echo "string1") <(echo "string2")

Hi, I am having problems in setting timeout in command and getting stdout at the same time. I used your example, and it works but I can't get output from this command:

 c := sh.Command("sleep", "3"); c.Start(); c.WaitTimeout(time.Seocnd)

I can use Output() function to get output but then timeout is not working.

sh.Command("sh", "-c", fmt.Sprintf("oc delete all -n %v %v", namespace, labels)).
Command("sh", "-c", fmt.Sprintf("oc delete service -n %v %v", namespace, labels)).
Command("sh", "-c", fmt.Sprintf("oc delete configmap -n %v %v", namespace, labels)).
Command("sh", "-c", fmt.Sprintf("oc delete secret -n %v %v", namespace, labels)).
Output()

not return

such as this
cat file.txt >> test.txt

// the following code is from pipe.go
func (s *Session) WaitTimeout(timeout time.Duration) (err error) {
select {
case <-time.After(timeout):
s.Kill(syscall.SIGKILL)
return ErrExecTimeout
case err = <-Go(s.Wait):
return err
}
}

func Go(f func() error) chan error {
ch := make(chan error)
go func() {
ch <- f()
}()
return ch
}

if timeout happends, go func() {ch <- f() }(), will never return, since
A receive from an unbuffered channel happens before the send on that channel completes.

out, err := sh.Command("./1", sh.Dir("/opt/wdsf/1/")).Output()
	fmt.Println(string(out), err)

fork/exec ./1: exec format error

Hello,

Can you please make a release with the current master code so it can be used with https://github.com/golang/dep

Thanks

When I run a command, that have Multiline-Output I get an Error:

.\main.go:6:21: newline in string
.\main.go:6:21: syntax error: unexpected newline, expecting comma or )

Line 6 in main.go is the import to this libary.

Hello!
i tried use this:

package main

import (
    "github.com/codeskyblue/go-sh"
    "log"
    "fmt"
)

func main() {
    port := uint(1)

    session := sh.NewSession()
    session.ShowCMD = true
    out, err := session.Command("/Users/Ivan/Downloads/redis-3.2.3/src/redis-server", "--port", port).Output()
    if err != nil {
        log.Fatal("ERROR: ", err)
    }
    fmt.Println("output is", string(out))
}

And have result:

/usr/local/go/bin/go run /Users/Ivan/Documents/GolangSpace/src/examples/test.go
[golang-sh]$ /Users/Ivan/Downloads/redis-3.2.3/src/redis-server --port

*** FATAL CONFIG FILE ERROR ***
Reading the configuration file, at line 2

Bad directive or wrong number of arguments
2016/09/09 15:55:25 ERROR: exit status 1

I need to execute make from go-sh, but I get this

configure: Setting lib to 'lib' (the default)
configure: Will try -pthread then -lpthread to enable POSIX Threads.
configure: CHECKS for site configuration
checking for gcc... gcc
checking whether the C compiler works... no

i.e. it can't find C compiler, I also checked $PATH and got an empty string

any idea how to make it work?

Im encountering a issue where a exit status 1 command gives output to the console.

This is a issue for me as i need a specific text to appear in the console rather than the command output (the reason for this is, its used for a monitoring check and expects a certain syntax).

The pseudo example code is:
`
package := "randompackage"

output, err := sh.Command("dpkg-query", "--showformat='${Version}'", "--show", package).Output()
fmt.Println(err)
`

This will result in the following output in the console
dpkg-query: no packages found matching randompackage <------------- This being the commands failing output
exit status 1 <------------- This being the fmt.println

Let me know if you want any other info

Is there anyway to mute the output ?

we may want to execute by admin account or other account

Support such as "tail -f", "less"?
