Hi,

i'd like the result of the following command:

$GROUPID | sed -e 's/\./\//g'

to assign to a variable:

TEMP="$GROUPID | sed -e 's/\./\//g'" ???
or
TEMP=[$GROUPID | sed -e 's/\./\//g'] ???

What is the correct command?

Thanks in advance!
Daniel

backticks?
TEMP=`$GROUPID | sed -e 's/\./\//g'`

The syntax is:

variable=`command arguments`

or:

variable=$(command arguments)

so you could use:

TEMP=$(echo "$GROUPID" | sed -e 's/\./\//g')

Using sed to do the subsitution may not be the most efficient way to do it,
depending on which shell you're using, e.g. in bash:

$ x="a:b:c"
$ y="${x//:/,}"
$ echo "$y"
a,b,c

so you may be able to just do:

TEMP="${GROUPID//.//}"

Note also that by convention all-upper-case names are only used for exported
variables.
