Remove word from bash string

Question

I have a line

file="this-is-a-{test}file"

I want to remove {test}

from this line. I used

echo $file | sed 's/[{][^}]*//'

but it brought me back

this-is-a-}file

How can I delete }

too?

thank

Also try using bash only oneliner as an alternative:

s="this-is-a-{test}file"
echo ${s/\{test\}/}

You can use sed

with the correct regex:

s="this-is-a-{test}file"
sed 's/{[^}]*}//' <<< "$s"
this-is-a-file

Or this awk:

awk -F '{[^}]*}' '{print $1 $2}' <<< "$s"
this-is-a-file
