检查stdout或stderr [英] Check for stdout or stderr
问题描述
我在Shell脚本中使用的二进制文件之一导致分段错误(返回值:139)
One of the binaries which I am using in my shell script is causing a segmentation fault (RETURN VALUE: 139)
尽管我将stdout和stderr都重定向到了一个日志文件，但是当我运行shell脚本时，在终端中会显示Segmentation Fault错误消息.
And even though, I am redirecting both stdout and stderr to a logfile, the Segmentation Fault error messages is displayed in the terminal when I am running the shell script.
是否可以将此消息从Segfault重定向到日志文件?
Is it possible to redirect this message from Segfault to a logfile ??
推荐答案
Well, I am answering my own question.. :) I found the answer here How can I suppress the output due to a SIGSEGV or a SIGFPE in a Fortran 90 program?
诀窍是添加
`exec 2> filename`
在外壳程序脚本中.
这会将所有消息从外壳重定向到日志文件
This will redirect all the messages from the shell to a log file
