Subject: Script broken after updating bash to 4.3.46-7?
Date: Sat, 27 Aug 2016 10:28:00 -0000 [thread overview]
Message-ID: <CAPTiy3PW0+bk20d30-J=sLr=PPnFOeU0Fb495hh1bBVtbtPrzw@mail.gmail.com> (raw)
After I updated Cygwin yesterday, a daily database backup bash script
(`automysqlbackup`) broke.
My previous bash was 4.3.42-4 (installed when I updated Cygwin on
2016/07/23), current is 4.3.46-7.
Here's the code snippet:
```bash
local i;i=0;
while read -r; do alldbnames[i++]="$REPLY"; done < <(mysql
--user="${CONFIG_mysql_dump_username}"
--password="${CONFIG_mysql_dump_password}"
--host="${CONFIG_mysql_dump_host}" "${mysql_opt[@]}" --batch
--skip-column-names -e "show databases")
```
This is supposed to get the list of all databases. Before it worked.
Now every item on the list ends with the CR character ($'\r'), causing
a bunch of issues with further script opreation. I'm using official
MariaDB Windows x64 binaries.
Frankly if mysql does output CRLF line endings, I don't know why that
script worked before, considering that this command in an interactive
shell produces a similar result:
```bash
# echo $'information_schema\r' | { read -r var; echo "{$var}"; }
}information_schema
```
But it did work somehow... Question is - what made it stop working
now, and what would be best way to fix it?
Regards,
Gene.
