[opensuse] error Output
I have a script that counts the number of files in a certain directory. The command I use is: NUMFILES=`ls mhc_er* | wc -l` When there are no files, the script returns the message: /bin/ls: bar*: No such file or directory I tried adding 2>/dev/null, but I still get the message. The syntax I used was: NUMFILES=`ls mhc_er* | wc -l` 2>/dev/null What should my syntax be for this line ? I would like to change it on this line inside the script, and not outside the script (I don't want to run ./myscript 2>/dev/null) Dirk *** Disclaimer *** The information contained in this e-mail is confidential and legally privileged and is intended solely for the addressee and to others who have the authority to receive it.

Maybe you meant "ls -l mhc_er* | wc -l" ?
When there are no files, the script returns the message:
/bin/ls: bar*: No such file or directory
I tried adding 2>/dev/null, but I still get the message. The syntax I used was:
NUMFILES=`ls mhc_er* | wc -l` 2>/dev/null
Try this: NUMFILES=`ls -l mhc_er* 2>/dev/null | wc -l` /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You'd rather want to use find . -name 'mhc_er*' | wc -l

But that's not the same. Your statement would also count files in subdirectories, whereas his only in the local directory. To use find to the same effect, one would need to add -maxdepth N to the options; N being 0 or 1, I'd need to read the find man page for that tidbit but am too lazy... ;-) Joachim -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Joachim Schrod Email: jschrod@acm.org Roedermark, Germany -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
Great, thank you very much for all the replies. I used the following in my script, which works very well for me.
