sh is a library to let you coding go like a shell script.
Examples
package main
import (
"os"
"strings"
"github.com/jopbrown/sh"
)
func init() {
// set -e
sh.SetExitOnError(true)
// set -x
sh.SetXtrace(true)
}
func main() {
// echo "$#"
sh.Echof("%d", sh.ArgN()).Print()
// echo "$0"
sh.Echo(sh.Arg(0)).Print()
// echo "$1"
sh.Echo(sh.Arg(1)).Print()
// for arg in $@; do
// echo $arg
// done
sh.FromSlice(sh.Args()).Print()
// pwd
sh.Echo(sh.Pwd()).Print()
// echo "$PATH"
sh.Echo(os.Getenv("PATH")).Print()
// rm -rf tmp*
sh.Rm("tmp*")
// ls
sh.Ls().Print()
// ls *.go
sh.Ls("*.go").Print()
// mkdir -p tmp tmp2
sh.Mkdir("tmp", "tmp2")
// cp *.go tmp/.
sh.Cp("*.go", "tmp/.")
// cp -r tmp tmp3
sh.Cp("tmp", "tmp3")
// mv tmp/*.go tmp2/.
sh.Mv("tmp/*.go", "tmp2/.")
// pushd tmp2
sh.Pushd("tmp2")
// touch 1.txt 2.txt
sh.Touch("1.txt", "2.txt")
// if [[ -e 1.txt ]]; then
// echo "exist"
// fi
if sh.Exists("1.txt") {
sh.Echo("exist").Print()
}
// if [[ -f 1.txt ]]; then
// echo "file exist"
// fi
if sh.ExistsFile("1.txt") {
sh.Echo("file exist").Print()
}
// if [[ -d 1.txt ]]; then
// echo "dir exist"
// fi
if sh.ExistsDir("1.txt") {
sh.Echo("dir exist").Print()
}
sh.Ls("*.txt").Print()
// ls *.txt
sh.Rm("*.txt", "*.go")
// rm *.txt *.go
sh.Popd()
// popd
// pushd tmp3
sh.Pushd("tmp3")
// grep 'func' main.go
sh.Grep("func", "main.go").Print()
// cat *.go | grep 'func'
sh.Cat("*.go").Grep("func").Print()
// sed -e 's/func/xxxx/g' main.go > main2.txt
sh.Sed(func(s string) string {
return strings.ReplaceAll(s, "func", "xxxx")
}, "main.go").PrintToFile("main2.txt", false)
// cat main.go | sed -e 's/func/ssss/g' >> main2.txt
sh.Cat("main.go").Sed(func(s string) string {
return strings.ReplaceAll(s, "func", "ssss")
}).PrintToFile("main2.txt", true)
// tar zcvf xxx.tar.gz *
sh.Exec("tar", "zcvf", "xxx.tar.gz", "*").Print()
if sh.Err() != nil {
sh.Exit(-1)
}
// echo "xxxxx" | base64
sh.Echo("xxxxx").Exec("base64").Print()
// popd
sh.Popd()
}
