Enable or disable a task in shell script - linux

Question

I have a few executable files to execute one by one. e.g.
A_1.sh
B_0.sh
cs_2.sh
c_4.sh
3_d.sh
I can execute all files with the following script, but I can't able to disable one, if I don't need that.
#!/bin/sh
for type in \
A_1 \
B_0 \
cs_2 \
c_4 \
3_d
do
echo executing $type.sh
done
When I am disabling one e.g.
#!/bin/sh
for type in \
A_1 \
B_0 \
# cs_2 \
c_4 \
3_d
do
echo executing $type.sh
done
It is showing syntax error near c_4. How to handle it actually?

Answer 1

The simplest is to use Bash:
#!/bin/bash
arr=(
A_1
B_0
# This is a comment
# cs_2
c_4
3_d
)
for type in "${arr[#]}"; do
echo executing $type.sh
done
You can read from a here document and filter comments:
#!/bin/sh
while read -r -u 3 line; do
# Is a comment?
if grep '^ *#' <<<"$line"; then continue; fi
# Close fd3, on the safe side.
echo executing $type.sh <&3-
done 3<<EOF
A_1
B_0
# This is a comment
# cs_2
c_4
3_d
EOF
Or invert the logic, do a function:
run() {
echo executing $1.sh
}
run A_1
run B_0
# run cs_2
run c_4
run 3_d
