Suggestion: Use "unbuffer" to get by pipe buffer

[tenpin784]

When downloading a game, the buffer of the tee command makes it appear that the download has frozen. By adding unbuffer (from the expect package), it makes it so the status lines are printed out as they happen.

In functions/fn_install_serverfiles:

---

unbuffer ./steamcmd.sh +login "${steamuser}" "${steampass}" +force_install_dir "${filesdir}" +app_update "${appid}" +quit |tee .fn_install_serverfiles.tmp

unbuffer ./steamcmd.sh +login "${steamuser}" "${steampass}" +force_install_dir "${filesdir}" +app_update "${appid}" -validate +quit |tee .fn_install_serverfiles.tmp

unbuffer ./steamcmd.sh +login "${steamuser}" "${steampass}" +force_install_dir "${filesdir}" +app_update "${appid}" -validate +quit |tee .fn_install_serverfiles.tmp

---

Just a thought.

NIce suggestion. I will be implementing this idea. Thanks

Looked at this however you have to install another package to get this to work and when I did the command still wasn't available in ubuntu or debian. Are there other options that are more compatible?

[tenpin784]

Did you install expect, or expect-dev?

From what I have read, in Ubuntu its in expect-dev.

that would be the issue then. I will look at writing this in as an optional. If the server happens to have it installed then it would use it. If not it wont.

[tenpin784]

Was thinking that too.

something like unbuffer=which unbuffer

if $unbuffer == '' then dont use it.

something like that?

yep thats what I have planned :). Won't take look long to implement either

You have a similar command in Linux it's part of the coreutils so it will be present on every system.

The command is stdbuf, take a look at http://linux.die.net/man/1/stdbuf

So for the case above to work you would do it like this.

stdbuf -o 0 <command> | tee <log_file>

[dgibbs64]

Thanks for that @ilijamt I will investigate.

Tried sdbuff got the following error

ERROR: ld.so: object '/usr/lib/coreutils/libstdbuf.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.

[dgibbs64]

I have now implemented unbuffer that will run if available on the distro.

This is an error with the files installed it's trying to load 32 bit but it's loading 64 bit.
This is some error with your distribution.

[dgibbs64]

Makes sense as im running 64-bit but ./steamcmd.sh is 32-bit.

[dgibbs64]

The only way to implement stdbuf would be to detect if a 32-bit version is installed and use that. otherwise it will just not use it.
