Hey all, I was hoping someone could help me with a little issue I've been having. I have over 200 files, and I want to trim them all up to the first appearance of a specific string. I need a batch file for command prompt, or even quickbms, to do this preferably.
Basically I want to do this for all files.

Go from
"miscellaneousclutterCTPKfollowed"
to
"CTPKfollowed"

Essentially I want to delete everything in the file BEFORE the string "CTPK" appears.

Can anyone help?

something like this, probably you want to "work" on the NAME variable:

Code:

findloc OFFSET binary "CTPK"
get SIZE asize
math SIZE - OFFSET
get NAME filename
log NAME OFFSET SIZE

All right, that works. Thanks much. On a minor addendum to this, how would one go about specifying that the SECOND occurrence of a string is the one that needs to be trimmed to? For example:

"miscellaneousdataTGXTmoredataGXTfollowing"
to
"GXTfollowing"?

Replace:

Code:

get SIZE asize

with

Code:

goto OFFSET
findloc SIZE binary "THE OTHER PATTERN YOU WANT TO SEARCH"
math SIZE - OFFSET

It's important that the second pattern is different than the first one or you will find it again, if it's the same it's enough to add a "getdstring DUMMY 4" before the above code to skip the first pattern found.

It doesn't seem to be working. Basically what I need to do is delete everything in the file before the EXACT string "GXT" is found, including the "TGXT" being deleted.

Ok, one quick question, how would I go about deleting everything up to and INCLUDING the first "3DS-LZ" in a file?

Code:

findloc OFFSET string "3DS-LZ"
math OFFSET   6
get SIZE asize
math SIZE - OFFSET
log "new.dat" OFFSET SIZE
