Errors in bash scripts

Question

I have a couple of errors in my script which I built in CentOS then deployed to Unix. I have the shebang #!/bin/bash on top of my scripts and execute my script using bash myscript.sh

LINE in script:

 existing[0]=""

ERROR: existing[0]=: not found

LINE in script: not sure if its this -

while IFS='' read -r line || [[ -n "$line" ]]; do

or this one -

if [[ $sftp_status != 0 ]]; then

ERROR: syntax error at line 118: `i=$' unexpected

LINE in script:

i=$((i + 1))

Apologies as I cannot extract the whole script here. It's currently in some server which I cannot pull out. — mtryingtocode

if you have the shebang line on top, you can set the execute permission and run the script as ./<scriptname>. You dont need the bash <scriptname>.

Those syntax seems to valid to me and i will doubt if this is bash. Try /bin/bash <scriptname> and see if it helps.

Yeah, I don't think this is coming from bash either. In particular, I can't find "at line" in the bash executable (either bash v3 or v4), so I'm pretty sure those error messages are coming from something else.

I had to replace those sections with double brackets [[ ]] with just single brackets []. Still suspicious though how come it fails on bash syntax
