sed problem any on help

when I execute the following expression
the sed don't work and the system don't give any error....why

if [ $d1=$d2]
echo "hi"
echo "$f"|sed -e 's/'"$g"'/'"$j"'/' -e 's/'"$b"'/'"$a"'/'>>file1

what is that you are trying to achieve ?

Is the ' if ' condition set to true such that sed is getting executed ?

Could you give us an example on sample input and output ? Smilie

Well, if g,j,b,a are having some values assigned, then your sed statements looks good to me, the output should be in the file1.

And if g,j,b,a are not having any value assined, you should get an error message like this
.. no previous regular expression

Your way of replacement is also correct, no issues.
So best will be, if you provide some more inputs to us, as matrixmadhan stated.

[jsaikia] ~ $ g="jadu";j="JADU";b="saikia";a="SAIKIA";echo jadusaikia|sed -e 's/'"$g"'/'"$j"'/' -e 's/'"$b"'/'"$a"'/'

[jsaikia] ~ $ g="jadu";j="JADU";b="saikia";a="SAIKIA";echo jadusaikia|sed -e "s/$g/$j/" -e "s/$b/$a/"
