How can I redirect my grep to a txt file, located in another directory?

Question

grep -n '[0-9]' test.txt > output.txt

I would like to redirect the above grep results on to a new file (not yet created, output2.txt ), which needs to be located in another directory than the directory of test.txt . For example, maybe at nothome/labs/output2.txt . How can I do this?

Answer 1

您可以将绝对路径放置到输出中，如下所示：

grep -n '[0-9]' test.txt > /path/to/output/output.txt

Answer 2

From your posting I guess you might want to create the output path first:

OUTPUT_PATH=/path/to/output
mkdir -p ${OUTPUT_PATH}
grep -n '[0-9]' test.txt > ${OUTPUT_PATH}/output.txt
