Hi,

I have an /etc/hosts where I want to change IP addresses but my problem
is that the separator can be multiple spaces or multipe tabs.

=====etc/hosts===
10.244.200.1 sapas2 SAPAS2
10.244.201.17 prevcs PREVCS
10.244.200.6 sapas3 SAPAS3
10.244.200.9 sapas4 SAPAS4
10.244.201.11 sapas1 SAPAS1 sapmsgsrv
10.244.201.12 prodvcs PRODVCS
10.244.201.33 sapps0 SAPPS0
10.244.201.15 oraaq1 ORAAQ1
#10.244.201.18 sapaq1 SAPAQ1
#10.244.201.26 saptc1 SAPTC1
#10.244.201.29 sapdv1 SAPDV1
10.246.17.114 sapaq1 SAPAQ1
10.246.9.112 saptc1 SAPTC1
10.246.17.110 sapdv1 SAPDV1
=====

example:
How to change the 10.244.200.1 ip address Only knowing that separator
would be spaces or tabs.

sed 's/10\.244\.200\.1 /192\.168\.10\.1 /' works only if there is a
space after the address!!

Any help would be appreciated.

thanks

sed is off-topic (and useless)

I think what you want is:

BEGIN { OFS="\t" }
sub(/10\.244\.200\.1/,"192.168.10.1",$1)+1
