The followmnmg will do what you are after:
Code:
COLLISIONCOUNT=`/sbin/ifconfig eth0 | grep "collisions"`
COLLMAX=99
if [ ${COLLISIONCOUNT} -gt ${COLLMAX} ] then
  echo "Collision count is greater than ${COLLMAX}!"
else
  echo "Collision count is less than than `expr ${COLLMAX}+1`!"
fi

It is the ` characters that run what is inside them and cause the output to be passed to the variable before the equals sign.

NAME
echo - echo (print) arguments SYNOPSIS
[arg] ... DESCRIPTION
writes its arguments separated by blanks and terminated by a new-line on the standard output. It also understands C-like escape conven- tions; beware of conflicts with the shell's use of write an alert character backspace print line without appending a new-line form-feed new-line carriage return tab vertical tab backslash the 8-bit character whose ASCII code is the 1-, 2-, 3- or 4-digit octal number n, whose first character must be a zero. write an 8-bit value that is the zero-, one-, two- or three-digit octal number num is useful for producing diagnostics in command files and for sending known data into a pipe. Notes Berkeley differs from this implementation. The former does not implement the backslash escapes. However, the semantics of the escape can be obtained by using the option. The echo command implemented as a built-in function of follows the Berkeley semantics (see csh(1)). EXTERNAL INFLUENCES
Environment Variables determines the interpretation of arg as single and/or multi-byte characters. If is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty vari- able. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See environ(5). International Code Set Support Single- and multi-byte character code sets are supported. AUTHOR
