在使用XAMPP运行的mac os shell脚本中发生MYSQL mysqldump错误

Question

I'm trying to run the following script through the command line on my mac mojave 10.14.3 running xampp 7.2.12-0:

    #!/bin/sh
PATH=/usr/local/bin:~/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Application/XAMPP/xamppfiles/bin

#----------------------------------------------------
# a simple mysql database backup script.
# version 2, updated March 26, 2011.

# (1) set up all the mysqldump variables
database="mybackup"
backupdir="."
backupuser="root"
day=`date +%u`
mkdir -p $backupdir/$day
 echo -n "Exporting $database..."
 mysqldump --opt --user=$backupuser --all-databases > ./$day/$database.sql
 echo -n "compressing..."
 gzip ./$day/$database.sql
 echo "done"

Executing this script generates the following command line error:

backup1.sh: line 22: mysqldump: No such file or directory

When I run the mysqldump command directly, it is executed properly. Does anyone have any thoughts on what I'm doing incorrectly?

The permissioning follows:

drwxrwxrwx+ 8 777       admin       256 Mar 16 08:44 .
drwxrwxrwx  4 777       admin       128 Mar 14 22:13 ..
-rw-r--r--@ 1 myLaptop  admin      6148 Mar 15 22:17 .DS_Store
drwxr-xr-x  7 myLaptop  admin       224 Mar 16 08:54 5
drwxr-xr-x  5 myLaptop  admin       160 Mar 16 09:18 6
-rwxr-xr-x@ 1 myLaptop  admin      1348 Mar 15 18:22 backup.sh
-rwxrwxrwx@ 1 myLaptop  admin       878 Mar 16 09:18 backup1.sh

Any help, much appreciated!!

Answer 1

If I delete

PATH=/usr/local/bin:~/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Application/XAMPP/xamppfiles/bin

then the script works.

Go figure?
