Re: Separating a scalar for searching

perldoc -f split perldoc perlretut You can use split on the comma character to get the individual fields in list context (store to an array or hash for example) and then step through the list searching on each. Or possibly a better approach if your data will allow it, search on the whole line a

Separating a scalar for searching

I am developing a search engine for a database I use. The database is static and consists of comma delimited files. After reading the text line-by-line into a scalar, I would like to analyze the data by field. How could I separate the fields or, at least, analyze them separately against a search

file locking before move?

I am using File::Copy to move a file from one directory to another. However, I do not want to move the file if it is being written to (by another program). Do i need to lock the file before moving it or does File::Copy by nature wait until a file is not being written to before moving? I lo

Use of Search::Dict

Can anyone point me to an example of how to use the above module? The ActiveState documentation is, to say the least, cryptic. I looked at "The PERL Cookbook", "PERL Programming", and also tried using PERLDOC, but did not come up with anything. Some of my questions are: 1. How should the inpu

I have an application that needs to attach to some data which it is running. I initially started by using Storable.pm and see a potential problem with data synchronization between different applications running. I think I need to change this to another type of data IO method. My first guess is
