 +===== Advanced Example =====
 +  * :!: remember to escape parenthesis when using [[sed]]
 +  * this example finds all occurrences of 'oldhostname' where it is not followed by a period, and replaces it with 'newhostname' 
 +<code>
 +grep -Z -R -l -E 'oldhostname[^\.]' . | xargs -0 sed -i 's/oldhostname\([^\.]\)/newhostname\1/g'
 +</code>
 +
 +===== FreeBSD 5 Example =====
 +  * the -Z parameter was different for grep, so it actually wanted %%--null%%
 +  * the backup extension for sed was not optional, so '.sed' was used
 +<code>
 +grep --null -R -l -E 'oldhostname[^\.]' . | xargs -0 -t sed -i '.sed' 's/newhostname\([^\.]\)/xdev\1/g'
 +</code>
