我有一个脚本，它通过写入同一个控制台行来显示节目的上传进度。当脚本从cron作业运行时，我得到许多行，而不是写入一行：
*** E0710091001.DAT *** [0.67%]
*** E0710091001.DAT *** [1.33%]
*** E0710091001.DAT *** [2.00%]
*** E0710091001.DAT *** [2.66%]
*** E0710091001.DAT *** [3.33%]
*** E0710091001.DAT *** [3.99%]
*** E0710091001.DAT *** [4.66%]
*** E0710091001.DAT *** [5.32%]
*** E0710091001.DAT *** [5.99%]
*** E0710091001.DAT *** [6.65%]
*** E0710091001.DAT *** [7.32%]
*** E0710091001.DAT *** [7.98%]
*** E0710091001.DAT *** [8.65%]
*** E0710091001.DAT *** [9.32%]
*** E0710091001.DAT *** [9.98%]
*** E0710091001.DAT *** [10.65%]
*** E0710091001.DAT *** [11.31%]
*** E0710091001.DAT *** [11.98%]
*** E0710091001.DAT *** [12.64%]
*** E0710091001.DAT *** [13.31%]
*** E0710091001.DAT *** [13.97%]
*** E0710091001.DAT *** [14.64%]
*** E0710091001.DAT *** [15.30%]
*** E0710091001.DAT *** [15.97%]
*** E0710091001.DAT *** [16.63%]
*** E0710091001.DAT *** [17.30%]
*** E0710091001.DAT *** [17.97%]
*** E0710091001.DAT *** [18.63%]
我只想知道我是否可以从脚本内部判断它是否是从cron调用的，如果是，我不会显示这个输出。
最佳答案
见下面的代码。用您想要显示的内容替换我的打印报表。
import sys
if sys.stdout.isatty():
print "Running from command line"
else:
print "Running from cron"
