Gee is tool of stdin to each files and stdout. It is similar to the tee command, but there are more functions for convenience. In addition, it was written as go. which provides output to stdout and files. In this process, it has various processing functions for lines such as replace, prefix, and suffix, so it can be used as a pipeline configuration or as a utility for testing. For more information, see the usage and case of study below!

📚 Case of Study

gee with prefix and suffix

▶ cat urls | gee -prefix "curl -i -k " -suffix " -H 'Auth: abcd'"
curl -i -k -H 'Auth: abcd'
curl -i -k -H 'Auth: abcd'
curl -i -k  -H 'Auth: abcd'

Find and replace

▶ cat raw.txt | gee -find keep-alive
▶ cat raw.txt | gee -find keep-alive -replace close

Specify the maximum length of the file and save it in multiple files.

▶ wc -l http.txt

▶ cat http.txt | gee -chunked 500 output

Distribute each line sequentially to multiple files.

▶ wc -l http.txt

▶ cat http.txt | gee -distribute alice.txt bob.txt charlie.txt
