I need to write a script that opens a file and either:

1) deletes the last line and replaces it. or alternatively.

2) compares the last line and if it is not equal to what I need it to be then it replaces it. I think option 1 will be simpler, so I'm going with that. However, the line that I need to inset must have the file name in it. ie: File name ABCD Replaced Line: <xxxx.xxx.xxx.xxx, "xxx", xx_ABCD, xxx="">

so I open my file by: 
#Takes file name from command prompt
#Then assigns the name to str fileName
$fileName = INFILE;

#open the file and copy to an array
open(INFILE) || die("Cannot Open File");
@aFile = <INFILE>;
close(INFILE);


# How do I get the script to continue if line 6 is
# already deleted?
# Delete line 6
splice(@aFile,5) || die("Line 6 is already deleted");

This is where I am stuck. I need to append the end of the file with a long string (see example above) that includes the file name. How difficult would it be to implement a test of the last string and output if the change had been made or not? Any assistance would be greatly appreciated. Thanks in advance
