Gimp Horizontal Flip

Automate Horizontal flip by command line single and secure

First:

#!/bin/bash

for f in "$@"; do
    # Extract path, filename, and extension
    DIR="$(dirname "$f")"
    FILE="$(basename "$f")"
    NAME="${FILE%.*}"
    EXT="${FILE##*.}"

    OUTPUT="$DIR/${NAME}_flipped.$EXT"

    gimp -i -b "(let* (
      (image (car (gimp-file-load RUN-NONINTERACTIVE \"$f\" \"$f\")))
      (drawable (car (gimp-image-get-active-layer image)))
    )
    (gimp-item-transform-flip-simple drawable ORIENTATION-HORIZONTAL TRUE 0)
    (gimp-file-save RUN-NONINTERACTIVE image drawable \"$OUTPUT\" \"$OUTPUT\")
    (gimp-quit 0)
    )"
done

Second:

#!/bin/bash

for f in "$@"; do
    DIR="$(dirname "$f")"
    FILE="$(basename "$f")"
    NAME="${FILE%.*}"
    EXT="${FILE##*.}"

    OUTPUT="$DIR/${NAME}_flipped.$EXT"
    TMP="$(mktemp --suffix=".$EXT")"

    # Run GIMP flip
    gimp -i -b "(let* (
      (image (car (gimp-file-load RUN-NONINTERACTIVE \"$f\" \"$f\")))
      (drawable (car (gimp-image-get-active-layer image)))
    )
    (gimp-item-transform-flip-simple drawable ORIENTATION-HORIZONTAL TRUE 0)
    (gimp-file-save RUN-NONINTERACTIVE image drawable \"$TMP\" \"$TMP\")
    (gimp-quit 0)
    )" >/dev/null 2>&1

    # Check result
    if [ $? -eq 0 ] && [ -s "$TMP" ]; then
        mv "$TMP" "$OUTPUT"
        echo "✔ Flipped: $OUTPUT"
    else
        echo "✖ ERROR flipping $f"
        rm -f "$TMP"

Script service on Ubuntu

Install odoo as service

Step 1: Create a script

user  ~  vi /usr/local/bin/odoo-start.sh
#!/bin/bash
# Optional: Port forward example with socat (install via apt install socat)
#socat TCP-LISTEN:8080,fork TCP:localhost:8069 &
# Your Odoo command (example for Odoo 17)

#exec /path/to/odoo-bin -c /path/to/odoo.conf --addons-path=/path/to/addons -d your_db --workers=2

export PYTHONHOME=/usr/local # Or remove if not required
exec /home/user/Software/odoo-17.0/venv/bin/python3 /home/user/Software/odoo-17.0/odoo-bin --http-port=8070 -d casa17g4

Step 2: Create service

user  ~  vi /etc/systemd/system/odoo17.service
[Unit]
Description=Odoo 17 Service
After=network.target postgresql.service

[Service]
Type=simple
User=user
Group=user
WorkingDirectory=/home/user/Software/odoo-17.0
ExecStart=/usr/local/bin/odoo-start.sh
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target

Step 3: Run and Debug

sudo systemctl daemon-reload

sudo systemctl reset-failed odoo17

sudo systemctl start odoo17

sudo journalctl -u odoo17 -e # See error

sudo journalctl -u odoo17 -f # See live

Step 4: Set it for boot

systemctl list-unit-files --type=service --state=enabled | grep odoo

sudo systemctl enable odoo17

systemctl list-unit-files --type=service --state=enabled | grep odoo

sudo systemctl disable odoo17 # disable from boot list

Javascript DEBUG functions

Object.entries(obj)

const obj = { foo: "bar", baz: 42 };
console.log(Object.entries(obj)); // [ ['foo', 'bar'], ['baz', 42] ]

const obj = { foo: "bar", baz: 42 };
const map = new Map(Object.entries(obj));
console.log(map); // Map(2) {"foo" => "bar", "baz" => 42}

// Using for...of loop
const obj = { a: 5, b: 7, c: 9 };
for (const [key, value] of Object.entries(obj)) {
  console.log(`${key} ${value}`); // "a 5", "b 7", "c 9"
}

// Using array methods
Object.entries(obj).forEach(([key, value]) => {
  console.log(`${key} ${value}`); // "a 5", "b 7", "c 9"
});

const object = {
  a: 1,
  b: 2,
  c: 3,
};

console.log(Object.getOwnPropertyNames(object));
// Expected output: Array ["a", "b", "c"]

const object1 = {
  a: 'somestring',
  b: 42,
  c: false
};

console.log(Object.values(object1));
// Expected output: ["somestring", 42, false]
