rextract: command not found

[akarasulu]

Hi there! Thank you in advance for this great work. I got the following error:

xxxx@xxxxx:~/Projects/ioschedset# io-get-sched sdb
/usr/bin/io-get-sched: line 95: rextract: command not found
sdb:    

Coming from:

root@stein:~/Projects/ioschedset# find . -type f | xargs grep rextract
./io-get-sched:    SCHEDULER="$(cat "./${blockDev}/queue/scheduler" | rextract '[\[]([^\]][^\]]*)[\]]' '${1}')"

I searched everywhere and with apt-file, too, but nothing turned up for extract. Could you lend a hand?

Thanks much!!!

The rextract executable can't be found and executed by the script.

The search path for executables is found in the PATH environment variable, as a colon-separated series of directories to check.

Most likely when you are switching between your user account and the root account, this PATH variable is also changing to something which does not contain the rextract install directory.

If you are using virtualenvs, it is not active when you are running the script.

The simplest "just work" thing to do would be to copy rextract to /usr/bin.

If you cannot do that for operational reasons, you can ensure the PATH variable is correct from the root script. Or use a virtualenv.

The command "which rextract" will perform the PATH search, to help you.

Have a great day!

I reread the subject and saw this is a report on ioschedset.

Sorry, I wrote this reply thinking it was a report on rextract, which is another one of my projects.

It appears the issue is rextract is not installed.

You should be able to install it via pip, and the setup.py install of ioschedset should have installed it for you.

How did you install io-schedset?

If all else fails, https://github.com/kata198/rextract

Is the core project, and has a standard setuptools setup.py installation.

You can also just copy the rextract file itself, it is standalone executable.

Thanks, and let me know if this helps!
