use of cat command

[bri_tal]

Could someone please tell me how to list the applications currently running, using the 'cat' command

[nick1austin]

Seems like a strange thing to do.

You can get the ps command from here:
http://194.1.151.205/tivo-static/softwa ... .1/devbin/

'ps a' will list all tasks.
'ps u' gives additional detail about each task.

[nick1austin]

Once you have a process number (pid) you can use cat to get additional details.

For example for process 283:
cat /proc/283/environ

[bri_tal]

Here is the output of the ps a command

Code: Select all

[TiVo [p0] ~]# ps a
  PID TTY STAT TIME COMMAND
  411  p0 S    0:00 /bin/bash -login
  425  p0 R    0:00 ps a
[TiVo [p0] ~]#

and

Here is the output of the cat command

Code: Select all

TiVo [p0] /bin]# cat /proc/411/environ
cat: /proc/411/environ: No such file or directory
[TiVo [p0] /bin]#

Doesn't tell me what tivo functions are currently in operation. I must be doing something wrong

[mrtickle]

there are many switches to ps, try googling 'man ps'

'ps auxf' gives more processes and even shows which are the parent processes of each. Here's my output, with some columns removed for brevity:

Thanks MrT. What prompted my query, was the fact that I believed MFS_Ftp to be running but when I came to extract a show from TivoWeb (selecting VLC).
I received the message that MFS_FTP is not running. At the moment, I simply want to check out if this is really the case and I thought that there would be a cat command to confirm this.

[mrtickle]

Cool. To just check if it's running, you can pipe the output to grep so that only the lines that match will be displayed.

Code: Select all

ps ax | grep mfs


I get

Code: Select all

~ # ps ax | grep mfs
  138  ?  R   15:24 tivosh /var/mfs_ftp/mfs_ftp.tcl 3105 backgrounded
 4062  p1 SW   0:00 grep mfs

ie process 138 on my tivo is mfs_ftp

[bri_tal]

Great, thanks for that. Does YOUR output tell tou that mfs_ftp is NOT running ?

[nick1austin]

Not sure if this will help, but if you just want to transfer a ty file you can do that with newer versions of TivoWeb from the 'MfsStream' menu.

[bri_tal]

Hi Nick,

I am using TivoWebPlus version 2.1.b3 (UK-20120818) and can only find 'Extract' with 3 options for file type. I chose vlc but got the error message that mfs_ftp was not running. Can't find 'stream' menu

[mrtickle]

Great, thanks for that. Does YOUR output tell tou that mfs_ftp is NOT running ?

It tells me that is IS running (on process 138).

[bri_tal]

It tells me that is IS running (on process 138).

Well my output to the ps query is virtually the same as yours, apart from the proc no. but upon trying to extract a show (vlc format) tivo tells me msf_ftp is not currently running. (I can extract using ty)
