Maybe you should use the parameter password, not passowrd. But generally speaking, you don't use system if you want to feed something into a spawned command's STDIN - you use `open $fh, "\|-", "$program @args";` - you are out of luck, though, if a program reads directly from `/dev/tty` (e.g. `/usr/bin/passwd`).

Your not completely out of luck if it reads from the controlling tty directly but you will require stronger magic, such as Expect or IPC::Run which will run things on a pty. The cake is a lie. The cake is a lie. The cake is a lie.	[reply]

Well it looks like you mistyped the "password" keyword, so...	[reply]

sagarkha It's discourteous -- at best, and this may be such a case -- to amend something you've posted without including a notice to that effect. So, since you didn't, here's a notice: Parent node's spelling error (noted by respondents above) was corrected without notice by OP "<node id="855733" title="How to enter passowrd through a file when it prompts on STDOUT." and "`system("mount -t smbfs -o username=sachins,domain=POWERSOFT,passowrd=***** //172.28.89.164/PS /mnt/test");`"	[reply] [d/l]

hey.. I too had experienced this kinda prob some time back... I dont exactly remember the syntax, but you can try adding the username and password of your windows machine into your linux machine, so that it never again asks for the pwd. Here is the procedure(google it if not correct) Login into RHEL machine as root, type the following commands: useradd -a <username of windows> <you would be prompter for the windows machine password> <enter the pwd again> Now run your script. Thats it... probably this might solve your prob.	[reply]
