alternative to the grep trick

Hi,

We used to use the below commands often.
Code:
ps -ef|grep [a]bc
ps -ef|grep abc|grep -v grep

Both fairly returns the same result.
For example, the process name is dynamic and we are having the process name in a variable, how we can apply the above trick.

For example "a" is the variable which contains the process name abc, then
Code:
ps -ef|grep $a|grep -v grep

This will work.
But how we can implement the other trick ,using [] in this case.
Any suggestions welcome.

Thanks.

XZGREP(1)							     XZ Utils								 XZGREP(1)

NAME
xzgrep - search compressed files for a regular expression SYNOPSIS
xzgrep [grep_options] [-e] pattern file... xzegrep ... xzfgrep ... lzgrep ... lzegrep ... lzfgrep ... DESCRIPTION
xzgrep invokes grep(1) on files which may be either uncompressed or compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed directly to grep(1). If no file is specified, then standard input is decompressed if necessary and fed to grep(1). When reading from standard input, gzip(1) and bzip2(1) compressed files are not supported. If xzgrep is invoked as xzegrep or xzfgrep then egrep(1) or fgrep(1) is used instead of grep(1). The same applies to names lzgrep, lze- grep, and lzfgrep, which are provided for backward compatibility with LZMA Utils. ENVIRONMENT
GREP If the GREP environment variable is set, xzgrep uses it instead of grep(1), egrep(1), or fgrep(1). SEE ALSO
grep(1), xz(1), gzip(1), bzip2(1), zgrep(1) Tukaani 2010-09-27 XZGREP(1)
