[CentOS] ls returns file doesn't exist, find finds it??
Howdy, I am getting some errors with find and ls command - such that find is able to see a file whereas ls says the file doesn't exist. Initially I was trying find and ls together as: # find ./ -type f -mtime +15 | xargs ls Similar behavior is seen even when I execute both commands separately. Any thoughts on what might be wrong here? -- thanks, neubyr ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] ls returns file doesn't exist, find finds it??
Thanks for the replies everyone. Les, you were right about meta-characters. The file name contains "double-quotes" (bad log4j config) and that's causing the problem. e.g. /opt/apps/tomcat/logs/apache.log\".-2010-09-24\" The ls command works fine after escaping double quotes: \" . My objective was to delete files matching find-pattern using 'xargs rm'. I wanted to do 'ls' before I delete these files permanently. I guess I can use 'find -delete' action instead which is working fine. -- neubyr.

Yup, the 'var' directory in path above is a nfs mount. Is there anyway
I can enable this?

[CentOS] NFS still serving old directory after rename
Howdy, I have renamed a directory on NFS ver 3 server and then created a new directory again with the same name. # mv dir dir-hosed # mkdir dir The directory is auto-mounted on client side. I had unmounted directories on client side before making above changes. Now when I try to mount back 'dir', I still see old files and not new empty dir. Am I missing something here in the NFS config? Is it caching old directory contents? Any help? thanks, neuby. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] NFS still serving old directory after rename
Seems like some clients (especially new connections) are mounting the new dir correctly. Not sure what's the problem though. -- thanks, neuby.

Not sure what was the problem, but it seems to be working now. I am guessing autofs or nfs had some timeout/cache settings that caused this problem initially.

[CentOS] figuring out LogVol details for mount
Hi, I need to mount a LVM in rescue mode to create a new initrd image. I am not sure how do I fond out which LogVol is to be mounted. How do I find it out? In most of the configs I have used LogVol00 with ext3 filesystem which contains OS install. This particular system is not installed by me and I am not sure how do I find it out. I did try 'lvm lvs' command, but probably that's not the right command here. Any help? -- thanks, neuby.r. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] xargs with max each line / argument
How do I pass xargs input one line at a time to subsequent command?
For example I want to install rubygems by reading a text file as shown
below, however the arguments are getting passed all at once to the
'gem install' command. I hace tried -L (max-lines) and -n (max args)
options, but it didn't work. What's missing here?? Any help?
$ cat gem.list.1
mkrf
rake
xmlparser
$ awk '{ print $0 }' gem.list.1 | xargs -L 1 -0 -I name sudo gem install name

Re: [CentOS] xargs with max each line / argument
Thanks for the help everyone. I used awk as the gem.list file may
contain version number in brackets - "rake (1.2)". I should have
mentioned this before. I used 'awk $1' to get first column from each
row. I liked all inputs, but I think I will try mark's awk solution
here. Thanks again..
