javashell传参数_shell脚本以及java调⽤shell并传参
在者就是java中怎样调⽤shell脚本 及怎样给shell传参
⽹上到好⼏种写法(实质都是Runtime().exec();⽅法不同重载形式):' v- a9 g, r/ @. a' }
shell代码
* O2 Y! h+ J: a$ Y
第⼀>>>>:String[] cmd = new String[length];
cmd[0] = "./shllName.sh";
for(int i =0; i < list.size(); i ++){ 2 Y0 m- Z1 A( s* \2 ^5 y& [" n+ v
/ w+ m: H+ T9 ?) B" W7 X" Z
cmd[i] = (i); //对字符串数组赋值(这就是给shell脚本传的参数) " c# z  S: j! x/ l; }# G) Z& T  M
: S+ G8 R+ ]9 V( Q1 h5 H0 p7 a
}
第⼆>>>:Sring[] cmd = {"/bin/sh/", "-c", "parma1", "param2"....};
第三>>>: 把调⽤shell及参数直接写在放在中即 Process pcs = Runtime().exec("sh shellName.sh 'param1' 'param2'...");. y- }1 W! x* ?0 `1 w
例⼦1:
Process pcs = Runtime().exec(cmd);    % q( H" B5 K4 X6 k6 b+ L! |
V8 D+ T' p8 T! w, R1 }
//若不加这下⾯的代码也调不成功shell脚本
InputStreamReader ir = new InputStream());    $ H9 O3 Z- |* G- S! W4 X2 _
LineNumberReader input = new LineNumberReader(ir);    9 v$ u& M' Y: v% f9 D
String line = null;
while ((line = adLine()) != null){
System.out.println(line);    & V0 D% z* t  E+ F/ l9 f8 W- H
}
if(null != input){
input.close();
}
if(null != ir){
ir.close();
}    1 A% b4 T" b3 v( }
int extValue = pcs.waitFor(); //返回码 0 表⽰正常退出 1表⽰异常退出
例⼦2， javascript 调⽤shell
String script = "cat /opt/local/apache-tomcat-6.0.26/webapps/deploy/";
StringBuffer outStr = new StringBuffer();
Process p = Runtime().exec(script);
InputStream processIn = p.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(processIn)); String input = null;
while( (adLine()) != null ) {
out.println(input);
