[LINUX] Creating a shell script to write a diary


This is an exercise in the shell script section of the Linux Primer, "New Linux Textbooks".


After running the shell, a file will be created to create today's diary.




#Create a data storage directory if it does not exist
if [ ! -d "$directory" ]; then
        mkdir "$directory"

#Assembling the diary file path
diaryfile="${directory}/$(date '+%Y-%m-%d').txt"

#If you don't have a diary file (if you're writing for the first time today), insert the date at the beginning
if [ ! -e "$diaryfile" ]; then
        date '+%Y-%m-%d' > "$diaryfile"

vim "$diaryfile"
-d file The file exists and is a directory
-e file File exists
