Script to add a fixed header to multiple .c/.h files

I would like to update all the files (.c / .h) of my project, using a script (for Linux), to add a fixed header of the following type:

Code:

---

/*
 * <File Name>
 * <Author>:                <Date>:
 *
 * Description:
 *
 * History:
 *
*/

---

How can I do ?

Something like this maybe:

Code:

---

cat $1 $2 > .tmp && mv .tmp $2

---

Running the script:

Code:

---

prepend preamble.txt file.txt

---

Yes, thank:

Code:

---

#!/bin/bash
for file in *.c; do
    cat $1 $file > .tmp && mv .tmp $file
done

---

Now it is a matter of reading the file name and inserting it in the header, then inserting the name of the author and reading the date of creation of the file, always inserting everything in the header. How you do it ?

At the moment I wrote this:

Code:

---

#!/bin/bash
for file in *.c; do
    echo "/*" > intestazione.txt
    echo " * File Name: " $file >> intestazione.txt
    echo " *" >> intestazione.txt
    echo " * Author: Giorgio Guglielmone    Date: " $date >> intestazione.txt
    echo " *" >> intestazione.txt
    echo " * Description:" >> intestazione.txt
    echo " *" >> intestazione.txt
    echo " * History:" >> intestazione.txt
    echo " *" >> intestazione.txt
    echo "*/" >> intestazione.txt
    cat intestazione.txt $file > .tmp && mv .tmp $file
done

---

instead of $ date I need to be able to use the bash date command to get the current bash script launch date. How should I write it ?

Code:

---

author='Your name here'
for file in *.c; do
  sed -i "s/<File Name>/$file/;s/<Author>/$author/;s/<Date>/$(date)/" $file
done

---

Code:

---

echo " * Author: Giorgio Guglielmone    Date: " `date` >> intestazione.txt
