Q.How do I redirect stderr to stdout? How do I redirect stderr to a file? A.Bash and other modern shell provides I/O redirection facility. There are 3 default standard files (standard streams) open: [a]stdin- Use to get input (keyboard) i.e. data going into a program. [b]stdout...
1–stdout, the standard output stream 2–stderr, the standard error stream There is an advantage in separating thestdoutandstderrstreams, as it allows to redirect/pipe a command’s output (stdout) to a file or anther command and still see any error messages (stderr) in the terminal. But...
>/dev/null 就是将标准输出和标准出错的信息屏蔽不显示 B.>/dev/null 2>&1 also can write as 1>/dev/null 2>&1 - stdout redirect to /dev/null (no stdout) ,and redirect stderr to stdout (stderr gone as well) . end up it turns both stderr and stdout off C.a little practice may ...
由上面的实验结果看出, 无论是标准输出 stdin 还是标准错误 stderr ,都被重定向到了 output.txt 里面。 1.5.2 使用 "&>" 把标准错误 stderr 重定向到标准输出 stdout ; echo -e "\e[42;31m --- Redirect stderr to stdout approach second ! ---\e[0m"; a* &> output.txt; -e "\e[1;32m...
1.4 Linux Shell 分别重定向标准输出 stdin 与标准错误 stderr 到指定的文件: echo -e "\e[42;31m --- Redirect stdout and stderr to exclusive files ! ---\e[0m"; cat a* 2>stderr.txt 1>stdout.txt; echo -e "\e[1;32m'cat a* 2>stderr.txt 1>stdout.txt' executed and return value...
另外,如果愿意,也可以将STDERR和STDOUT的输出重定向到同一个输出文件。为此bash shell提供了特殊的重...
