How do you remove the first letter of a value?

[brienhawker]

I have a list of usernames of varying lengths. I just need to have the first letter of each username removed. Im guessing it has something to do with ltrim but I dont know what to put in to remove the first random character.

Hi @brienhawker,

 .... | eval new_username=substr(username, 1)

Hi

try this

|makeresults |eval msg="sample" | eval result =replace(msg,"^.","")

Yes, ltrim can do it but get used to using sed like this:

... | rex field=username mode=sed "s/^.//"
