I am looking to create an acronym from a dynamic string, by capturing the first letter of each broken substring
How do I write the script, so I can capture whatever number of substrings gets generated from the original string?
ie. "Hello_World_Look_At_Me" => "HWLAM"
"Hello_World" => "HW"
I'm thinking of doing the following, but this seems to be pretty lengthy. Would like to know if there's a more efficient way of getting this done.
| eval txt1 = "Hello_World_Look_At_Me"
| eval tmp = split(txt1, "_")
| eval new_word = substr(mv_index(tmp,1), 1) + ...
Assuming words are always made of alphabetic letters, try something like this
| rex max_match=0 field=txt1 "(?<initial>[a-zA-Z])[a-zA-Z]*_?"
| eval new_word=mvjoin(initial,"")
Thanks!!! @ITWhisperer
