Split a line

Shell Programming and Scripting

I guess this has a simple solution but can't figure out now.

having:

x="H:a:b:c"

to get H:

echo $x|awk -F: {'print $1'}

how can I put REST of line in another one? i.e.

echo $rest

a:b:c

thanks

Well the hand icon should be a colon followed by a "b". Also lines have variable length.

Please use

 tags next time.
x="H:a:b:c"
var1=${x%%:*}
var2=${x#*:}

$ 
$ 
$ echo "H:a:b:c" | awk '{sub(/^[^:]*:/,"",$0); print $0}'
a:b:c
$ 
$ echo "H:a:b:c" | awk '{print substr($0,index($0,":")+1)}'
a:b:c
$

$ echo "$x"|sed 's/:/\n/'
H
a:b:c

or using danmero's (preferrable) sugggestion

$ echo "${x%%:*}"; echo "${x#*:}"
H
a:b:c

Scrutinizer could you please explain how Danmero's suggestion works?

Hi Eagl�, danmero's suggestion uses parameter expansion
