举例:shell的脚本:t.sh内容:echo "this is a test shell with arguments"echo "arg1 = $1; arg2 = $2;"凯伍尺执行脚本./t.sh zhao结果如下:[noncode@gnode108 knockdown_workflow]$ ./t.sh zhao1 zhao2this is a test shell with argumentsarg1 = zhao1; arg2 = zhao2;python脚本:[noncode@gnode108 knockdown_workflow]$ cat t.py #!/usr/bin/env pythonimport osimport sysdef main():print 'Hello world!'if len(sys.argv) < 2 : print "usage:%s config log" %(sys.argv[0]) sys.exit(1)arg0 = sys.argv[0]arg1 = sys.argv[1]print "arg0 = %s; arg1 = %s" % (arg0, arg1) print "test ./t.sh: "os.system('./盯高t.sh ' + arg0 + ' ' + arg1)print "test method of replacing: "t = 't.sh'm = 'zhao'n = 'zhao'cmd = "./%s %s %s" % (t,m,n)print "t = %s; m = %s; n = %s; cmd = %s" % (t,m,n,cmd)os.system(cmd)if __name__ == '__main__':main()运行脚本:python t.py t.sh执行结果:[noncode@gnode108 knockdown_workflow]$ python t.py t.shHello world!arg0 = t.py; arg1 = t.shtest ./t.sh: this is a test shell with argumentsarg1 = t.py; arg2 = t.sh;test method of replacing: t = t.sh; m = zhao; n = zhao; cmd = ./t.sh zhao zhaothis is a test shell with argumentsarg1 = zhao; arg2 = zhao;[noncode@gnode108 knockdown_workflow]$ cat t.sh echo "this is a test shell with arguments"echo "arg1 = $1; arg2 = $2;"[noncode@gnode108 knockdown_workflow]$ ./t.sh zhao1 zhao2this is a test shell with argumentsarg1 = zhao1; arg2 = zhao2;说明:两种方橘陪法使用python脚本调用shell脚本:第一种方法:os.system('./t.sh ' + arg0 + ' ' + arg1)注:./t.sh后面有一个空格,不同的第二种方法:t = 't.sh'm = 'zhao'n = 'zhao'cmd = "./%s %s %s" % (t,m,n)print "t = %s; m = %s; n = %s; cmd = %s" % (t,m,n,cmd)os.system(cmd)注:在之前把字符串聚合到一起。
