hi all,
i've a file named "a.config" with the line
"CLUSTER_NAME[\t][\t]cluster1" by [\t] i mean tabs.
now i need to change the value cluster1 to someother value, say autocluster. The code which i wrote was :
cat a.config | sed 's/CLUSTER_NAME[\t][\t] [A-Za-z0-9]*/CLUSTER_NAME[\t][\t]autocluster/' > a.config.temp
mv a.config.temp a.config
but this doesn seem to work, any idea on how to do it.
thanks in advance.
