Re: [go-nuts] Get array response back in golang
Insufficient information. It looks like your question involves handling
JSON data structures but beyond that no one is going to be able to provide
any useful advice. Can you provide a small code example for what you
have tried? Can you elaborate on what you mean by "in response"? Are you
making a HTTP request that returns JSON and you are having trouble parsing
the result into equivalent Go data structures?

[go-nuts] Question on 'cmd/compile: handle partially overlapping assignments' behavior on ARM64.
I stumbled across a performance regression on ARM64 for go 1.18.6 and
1.19.1 that wasn't present in earlier releases. In the following benchmark,
you can see `BenchmarkSliceOfArray` experiences a 70% increase in
execution time while `BenchmarkSliceOfInt` remains unchanged.
BenchmarkSliceOfArray 413121 2855 ns/op
BenchmarkSliceOfArray 216478 4881 ns/op
Through the use of `pprof` and `GOSSAFUNC go build`, it was observed that
the latest release employs `runtime.memmove` and accounts for the change in
performance. I don't see the invocation of `memmove` or the perfromance
degradation on AMD64.
I believe this can be traced back to -
https://go-review.googlesource.com/c/go/+/425234.
Is this new behavior in this scenario correct or unindented?
Should I open an issue for this?
I am a newbie, so forgive me if there are errors in my approach.

You first "search" is a go local variable.
Your second "$search" is seen by the shell as a reference to an environment
variable.
So if you want to do it that way, you need to set it in the environment,
e.g. with os.Setenv.

Try something like this, not tested:
cmd, err := exec.Command("bash", "-c", fmt.Sprintf("find . -name

[go-nuts] Using golang variable in bash script Command
HI everyone, can anyone help me with this:
I want to list all the files having some user's entered string as substring
in their name.
So I wrote these commands:
*scanner := bufio.NewScanner(os.Stdin)fmt.Println("Enter the substring
name")scanner.Scan()search:=scanner.Text()cmd1,err:=exec.Command("bash",
"-c", "find . -name '*$search*'")*
But I think the variable search is not getting used inside exec command.
Can anyone please let me know, how I can use the golang variable in bash
command this?
Thanks
