what Perl function can I used to invoke something usually done at the command line? I want to execute:
sum * > SNP/020405/foo.txt this will call checksum on everything and output to foo.txt in /SNP/020405. Problem is, the * will sum all files in the current directory, not those in SNP/020405. So then I'd instead use: sum SNP/020405/* > SNP/020405/foo.txt but the problem with this is the foo.txt will look like: 5134 1 SNP/020405/17D78401.001 instead of the much "cleaner": 5134 1 17D78401.001 I basically need to change directories to 020405 (chdir will do this ok), and then call sum * and output the results to a file which should also be located in 020405 (How do I do this part?). Thanks in advance for all help. -Jose -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
