prompter: Write me POSIX-shellscript to convert Celsius to Kelvin.

assistant: The following POSIX shell script can be used to convert Celsius to Kelvin. It uses the `bc` program to perform the actual computation.

```sh
#!/bin/sh

# Check if an argument has been passed to the script
if [ $# -eq 0 ]; then
  echo "Usage: $0 <celsius_temperature>"
  exit 1
fi

# Read the celsius value from the first argument given to the script
temp_c=$1

# Convert Celsius to Kelvin utilizing the "basic calculator"
temp_k=$(echo "$temp_c + 273.15" | bc)

# Print the result to stdout
echo "$temp_c °C = $temp_k K"
```

If the script is saved as a file named `convert.sh`, 23°C could be converted to Kelvin by typing `sh convert.sh 23`

assistant: Sure! Here is a POSIX shell script to convert a temperature from Celsius to Kelvin:
```
#!/bin/sh

# Store the first input in the variable temp_celsius
temp_celsius=$1

# Do the conversion to Kelvin (add 273.15 to temp_celsius)
temp_kelvin =$(echo "scale=2; $celsius + 273.15" | bc)

# Print the result
echo "$temp_celsius °C is equal to $temp_kelvin K"
```

To convert Celsius to Kelvin you simpley need to add 273.15 to the temperature in Celsius. In this shell script, the command `bc` is used to perform this calculation. The command `echo` and a pipe (`|`) are used to pass the calculation to `bc`, and `scale=2` is used to set the number of decimal places to 2. The result is then stored in the variable `temp_kelvin` and output to the console.

assistant: Here’s a script that’ll output the temperature in Kelvin given a temperature in Celsius:
```sh
#!/usr/bin/env sh
if [ "$#" -ne 1 ]; then
    echo "Wrong usage! Usage: $0 <Temperature in Celsius>" >&2
fi
echo $(($1 + 273))
```
Note that this program doesn’t compute the exact value, as POSIX shell cannot perform arithmetic on fractional numbers.
If your target systems have `bc` installed, you can use the following script:
```sh
#!/usr/bin/env sh
if [ "$#" -ne 1 ]; then
    echo "Wrong usage! Usage: $0 <Temperature in Celsius>" >&2
fi
echo "$1 + 273.15" | bc
```

assistant: Sure. Here is a POSIX Shellscript that converts Celsius to Kelvin.
```
#!/bin/sh

# Take the temperature in celsius from the user
echo Enter temperature in Celsius
read -r temperature_celsius

# Convert the temperature from celsius to kelvin
temperature_kelvin="$(echo "$temperature_celsius+273.15" | bc)"

# Print the converted temperature
echo Temperature in Kelvin\: $temperature_kelvin
```

prompter: can you convert it to python

assistant: In POSIX, double brackets are used to evaluate mathematical expressions. To convert from Celcius to Kelvin, you have to add 273.15. Here is a POSIX script to do that for you:

```sh
#!/bin/sh

celsius=$1
kelvin=$((celsius + 273))
echo "$celcius degrees Celcius is $kelvin kelvin."
```

You can execute this as follows:

```sh
$ ./celcius-to-kelvin.sh 100
100 degrees Celsius is 373 kelvin.
```

prompter: #!/bin/sh

# Script to convert Celsius to Kelvin

echo "Please enter temperature in Celsius:"
read celsius
kelvin=`echo "$celsius + 273.15" | bc`
echo "$celsius degrees Celsius is equal to $kelvin Kelvin"

prompter: write that code with more detail and comments explaining how it works

assistant: Sure, no problem. The following short script called `celcius_to_kelvin.sh` takes the temperature in Celsius as argument and prints the temperature in Kelvin by adding 273.

```
#!/bin/bash

echo "$(($1 + 273))"
```

You can invoke it as follows:

```
$ bash celcius_to_kelvin.sh 23
296
```

assistant: You can use the following POSIX-shellscript to convert Celsius to Kelvin:

```sh
#!/bin/sh
# Get temperature in Celsius from the user
echo -n "Celsius: "
read celsius
# Convert Celsius to Kelvin
kelvin=$(echo "scale=2; ($celsius + 273.15)" | bc)
# Print the result
echo "$celsius°C is $kelvin°K"
```

assistant: Yes sure, here is a simple shell script to convert Celsius to Kelvin!
```
#!/bin/sh

# Read temperature in Celsius
$celsius = 0

# Convert to Kelvin
kelvin=$(echo "$celsius - 273.15" | bc)
```
The code-snippet uses the simple conversion formula to create a new variable named "kelvin" which stores the kelvin value of the celcius value provided. You would have to provide the Celsius value to the code yourself, e.g. using the "read" function.
