files with extra suffix in batch -

i'm trying list files have suffix after extension e.g: .txt.1 or .txt.2 etc..

i'm using txt. it's giving file names instead of files suffix

for %%a in (*txt.*) (call :renum "%%a")

after i'm writing program rename files accordingly. can please check , help.

one solution filter extension inside loop:

for %%a in (*txt.*) (     if not "%%~xa"==".txt" call :renum "%%a" )

this works using "enhanced substitution of for variable references", in case %%~xa. can overview of available substitutions executing for /?.

update:

this solution not work case-insensitively, because neither explicitly demanded or prohibited. use if /i instead of plain if if case-insensivity desired.
as dbenham notes, there edge cases:
- name.txt.txt will not processed. if that's ok not stated, rather likely.
- name_txt.ext will processed, due given wildcard *txt.* , can avoided using *.txt.* instead. rationale not change in first place op knows actual set of files, , assumed had reason choosing (a situation common in these types of questions).
