Searching a folder with spaces via bash script

[nehasjains]

Installed mpd and mpc on my raspberry pi.

I want to search a folder(with spaces) in my library via mpc using bash script

#!/bin/sh
mpc --host=mypwd@127.0.0.1 --port=9999 ls $1

I am launching the script from terminal as follows
$ ./play.sh Bryan\ Adams

I am getting an error mpd error : No such directory.

Whereas if I run the mpc command directly from terminal as below mpc return the folder contents.

$ mpc --host=mypwd@127.0.0.1 --port=999 ls Bryan\ Adams

The command run from terminal fetches the result but if I run a bash script it gives error.

Kindly guide me how to fix this.

Thanks in advance.

The argument in your script should be quoted:

#!/bin/sh
mpc --host=mypwd@127.0.0.1 --port=9999 ls "$1"

Thanks a lot now its working...

mpc --host=mypwd@127.0.0.1 --port=9999 ls "$1" > /dev/null

I want to hide the output of the command of the directory is not found so using /dev/null but it's still displaying the output. Any way to hide the output? Also tried -q parameter

Possible you should also redirect STDERR.

#!/bin/sh
mpc --host=mypwd@127.0.0.1 --port=9999 ls "$1" 2>&1 > /dev/null

#!/bin/sh
mpc --host=mypwd@127.0.0.1 --port=9999 ls "$1" 2>&1 > /dev/null

Wow this worked.

I am a beginner in linux... any book you recommend

Really thank you for your kind help

Searching the internet should help ;)

[nehasjains]

Yes I agree but eg in this case I had no idea that there is something like "redirect STDERR". So if you can recommend any good book that would be great.

Old tutorial for bash [https://tldp.org/LDP/Bash-Beginners-Guide/html/Bash-Beginners-Guide.html] Redirection of errors [https://tldp.org/LDP/Bash-Beginners-Guide/html/Bash-Beginners-Guide.html#sect_08_02_03_02] BTW: bash is not a "linux-only" thing it is Unix ;)
