Question

I’m using a shell script that uses sed

I have this sentence in a variable

kpi="ENFRIADORA CONDENSADA POR AIRE/AIRE-AIRE/AGUA - MENSUAL" 

if in a console I put

echo $kpi | sed 's/\//\\\//g'

I see

ENFRIADORA CONDENSADA POR AIRE\/AIRE-AIRE\/AGUA - MENSUAL

That is what I want, but when I put this in a script like this

echo start
echo $kpi2
kpi_2=`echo $kpi2 | sed 's/\//\\\//g'`
echo $kpi_2
echo end

That I see is :

start
ENFRIADORA CONDENSADA POR AIRE/AIRE-AIRE/AGUA - MENSUAL
sed: -e expresion #1, character 9: unknown option to `s'

end

Any suggestion?

Answer 1

$> kpi_2=$( echo $kpi | sed 's/\//\\\//g' )

$> echo $kpi_2
ENFRIADORA CONDENSADA POR AIRE\/AIRE-AIRE\/AGUA - MENSUAL
