Top Forums Shell Programming and Scripting Finding consecutive numbers in version names on a txt file Post 302503879 by fox1212 on Saturday 12th of March 2011 06:44:17 AM

Ok, a sample. Say this is the text file resulting from the sorted list of the directory:

abcd-001.pdf
dfcd-003.pdf
grdr-001.pdf
grdr-002.pdf
hhgt-001.pdf
htfr-001.pdf
htfr-002.pdf
htfr-003.pdf
htfr-004.pdf
jkdyr-001.pdf
tasd-018.pdf
tasd-019.pdf
yrdf-003.pdf
zgdr-001.pdf


As you see, the file grdr-xxx has been versioned once, and so there's the 001 and 002 versions, and the htfr-xxx three times, so we have from 001 to 004.
The file tasd has also been versioned and we have the 018 and 019 version because in previous executions the 001 to 017 have already been deleted.

What I want is to extract from a file like this the old versions. That is, from the sample above, I want to return the following entries:

grdr-001.pdf
htfr-001.pdf
htfr-002.pdf
htfr-003.pdf
tasd-018.pdf

so I can move or delete them and keep only the last version.

David Kreil, Barak A. Pearlmutter, Yaroslav O. Halchenko BUGS
Using a web-based encoder server is a stop-gap measure until better encoders enjoy wide free distribution. There is a security issue in operating on documents not intended for widespread distribution, which could be partially although not com- pletely ameliorated by using a secure web connection. SEE ALSO
