remove file extension
Hi ALL,
I'm new to this forum.
Thanks and congrats to all for their great efforts building this site simply superb for all unix administrators.
My requirement is to remove extensions of the files in the current directory. I'm doing it using below script which is working but i think it is very inefficient as i use lot of variables.I want to get done by avoiding usage of tempfile file and any other temp files being used.
#!/usr/bin/bash
ls -l |awk '{print $9}' >/list
cat /list |while read line
do
echo $line >/tempfile
first=`cut -f1 -d'.' /tempfile`
echo $first >>/output.txt
mv $line $first
done
Thanks
Praveen RK

ccs_config_validate
CCS_CONFIG_VALIDATE(8) System Manager's Manual CCS_CONFIG_VALIDATE(8)
NAME
ccs_config_validate
DESCRIPTION
Usage:
ccs_config_validate [options]
OPTIONS
-h Print this help, then exit
-V Print program version information, then exit
-v Produce verbose output
Validating XML configuraton files:
-f configfile
Validate an alternate config file without preloading it with default values.
-l configfile
Validate an alternate config file with preloading of default values (recommended option).
Advanced options:
-r Force validation of runtime config
-C config_loader Override config plugin loader
-t tempfile
Force temporay file to tempfile
-n Do not remove temporary file
-o Overwrite temporary file (dangerous)
DEFAULT
Default operation for ccs_config_validate is to load the currently configured environment and verify the outcoming configuration.
Example 1: current environment uses a configuration file (/etc/cluster/cluster.conf).
The user modifies cluser.conf and executes ccs_config_validate without options. The tool will validate the modified cluster.conf
after including default values.
Example 2: current environment is set to load the configuration from LDAP. Users
modifies LDAP databse and before pushing the change to the nodes, she/he can issue ccs_config_validate to verify the contents o the
LDAP database automatically (as long as the correct LDAP environment is set in the cman/cluster sysconfig/defaults files).
