./pkg-search.sh: 2: ./pkg-search.sh: Bad substitution in a shell script -

[shirish शिरीष <shirishag75@xxxxxxxxx>]

Dear Friends,

Please CC me as I'm not subscribed to the list.

I have the following script -

─[$] cat pkg-search.sh
     1	for file in /usr/share/doc/*/changelog.Debian.gz; do
     2	    package=${file:15}
     3	    package=${package%%/*}
     4	    echo -n "$package "
     5	    date -d "$(zgrep "\\-\\- .* <.*>  .*" $file|tail -n 1|awk
'BEGIN { FS="  " } { for (i = 2; i <= NF; i++) { if (i > 2) printf "
"; printf "%s", $i } }')" +%s
     6	done | sort -k2,2nr -k1


Trying to run the script under zsh I get the following -

[$] ./pkg-search.sh
./pkg-search.sh: 2: ./pkg-search.sh: Bad substitution

I am running zsh 5.3.1

[$] zsh --version
                                                             [2:35:24]
zsh 5.3.1 (x86_64-debian-linux-gnu)

On Debian testing/stretch with the latest updates .

Look forward to know what's wrong in the above script.
