Top Forums Shell Programming and Scripting sed and special character in data Post 302161052 by jim mcnamara on Wednesday 23rd of January 2008 01:46:17 PM

sed treats & as the pattern space - in other words what sed found as a match for your regular expression. & as an operator means "print the pattern space".

One workaround without doing a lot of sed hacking is to change the & character to something else, then change it back using tr:
Code:
tr '&' '+' < a.txt > tmpfile
y=`echo $a$b$i`
z=`echo $a$b$i$b$x`
sed s/"$y "/"$z "/g tmpfile | tr '+' '&' > CusT_TmP
cat CusT_TmP a.txt
