IMPORTANT UPDATE: Cogent Core now has an improved version of etail in its ttail package. This version will not be further maintained or developed. The v1 version is still needed for the v1 version of emergent.
etail is a tail command for looking at .csv / .tsv log / data files in a terminal window.
This is a Go rewrite of the pdptail command written in perl, dating back to the PDP++ era.
This should install into your $GOPATH/bin dir:
$ go get github.com/emer/etailJust pass files as args, e.g., on the test files in this dir:
$ etail RA25*This is shown when you press h in the app:
