我对蟒蛇有点陌生。目标是使用子进程parse&；从shell检索打印输出。执行错误如下面的示例输出消息所示。下面还显示了示例代码片段
代码段：
testStr = "cat tst.txt | grep Location | sed -e /.*Location: //g "
print "testStr = "+testStr
testStrOut = subprocess.Popen([testStr],shell=True,stdout=subprocess.PIPE).communicate()[0]
输出：
testStr = cat tst.txt | grep Location | sed -e /.*Location: //g
cat: tst.txt: No such file or directory
sed: -e expression #1, char 15: unknown command: `/
是否有可以使用的变通方法或功能？
Appreciate your help Thanks
我想你的主要错误与python无关。更准确地说，有三种：
import subprocess.sed -e s/.*Location: //g . You wrote ///g instead of s///g.tst.txt does not exist.您应该直接将testStr作为第一个参数传递，而不是将其封闭在列表中。请参阅子进程。Popen，以“在Unix上，shell=True：。。。”。
