我试图将grep结果显示给终端以及一个文件。我提出的解决方案是只运行两次，但这显然会造成效率问题。
grep -n $ SEARCH_TERM$ i
grep -n$ SEARCH_TERM$ i>> /file.txt
是否有一个标签可以仅使用一次搜索打印？
谢谢 解决方案
您正在寻找的程序是tee ：
grep -n$ SEARCH_TERM$ i| tee -a /file.txt
I'm trying to display the grep results to the terminal as well as to a file. The solution I've come up with is to just run it twice, but this obviously will create efficiency issues.
grep -n "$SEARCH_TERM" "$i"
grep -n "$SEARCH_TERM" "$i" >> /file.txt
Is there a tag that will allow it to print to both using only one search?
Thanks
The program you are looking for is "tee":
grep -n "$SEARCH_TERM" "$i" | tee -a /file.txt
