Extract characters without digit

[royimad]

I have a field in the log like the following:
abc1232
ab.sadkjsakj21302139
abc3400349
alex.carl2103920

I need to extract all characters without the digital number. How to do that using regular expression? rex or interactive field extraction?

Thanks

If you are going to be using it repeatedly, I would place it in a props/transforms. But you can do it via search line.

|rex field=myfield "(?<no_digits>[^\d]*)"

OR with props.conf

[mysourcetype]
EXTRACT-myfield = (?<no_digits>[^\d]*) in myfield

Hello

You could use this regular expresion:

(?<mystring>\D+)

And using the rex command:

... | rex "(?< mystring >\D+)" | ...

*Without the spaces before and after the field name
