shell script
Hi All

Have to write a shell script for the follwing tasks:

1. Have to redirect three cmd outputs in three different files
ex: sar -u 1 10 >date.sar.txt
vmstat 1 10 >date.vmstat.txt
iostat 1 10 >date.iostat.txt

where date should be current system date as the output file name


Any help will be highly appreciated

Thanks

try this,

output of date would be used as such
Code:
cmd >  file."`date`".txt

Try this..,

Code:
Currentdate=`date +%Y%d%m`
echo $Currentdate

sar -u 1 10 > $Currentdate.sar.txt
vmstat 1 10 > $Currentdate.vmstat.txt
iostat 1 10 > $Currentdate.iostat.txt

or try this:

Currentdate=`date +%Y%d%m`
T="txt"
sar -u 1 10 > $Currentdate.sar.$T
vmstat 1 10 > $Currentdate.vmstat.$T
iostat 1 10 > $Currentdate.iostat.$T

I still could not figure out how to run following 3 cmds parallel to take output of same time

sar -u 1 10 > $Currentdate.sar.txt
vmstat 1 10 > $Currentdate.vmstat.txt
iostat 1 10 > $Currentdate.iostat.txt


Can anyone help?

In that case, a common filename as mentioned in the previous post should be used

and that should be visible to the other 2 process as well.

if the process' are run in parallel and not as sequential process, you might encounter that the ouput of the 3 process just flush in in to the file and might be garbled, which needs to be parsed and refactored later.
