Data different result on shell and on perl HELP NEEDED
hi i am using this command which would return to be the filename
Code:
ls -l $dir1 | awk '{print $9}'

however on perl when i use:
Code:
`ls -l $dir1 | awk '{print \$9}' > tmp`

it gives me a different result. Everything is the same however a directory does not contain the the forward slash so i cannot differentiate which is a file and which is a directory. By using the same command on command prompt i did not have this problem.

You have something in your environment (an alias, perhaps?) which is not there inside Perl. Seems like you probably have "alias ls=ls -F" or something to that effect in your shell. ls does not add these forward slashes by default, there's an option somewhere which does it for you.

oh thanks that solved my problem
it explains why the same command return different output now

i am new to the unix environment and the school have use alias to make it easier for us to use. In this case it really confuse me but something learnt i guess.

thanks once again ^^
