write-line new lines to existing file

[aaryan]

Hi All,

 

Help me know writing new lines to existing file.

eg. following line is existing in a file.

(write-line "Hello-World" "filename")

 

additional line to be written is

(write-line "Good Morning" "filename")

 

Thanks in advance

Aaryan.

the file name should be variable and not a string .

 

e.g .

 

(setq filename "Complete path of file name HERE")

(setq filename (open filename "w"))
(write-line "Good Moring honey " filename)
(close filename)

You should look to Append mode of OPEN function for files access.

Please try this code (don't remove the file):

(setq ff (open "C:\\test.txt" "w"))
(write-line "1st line" ff)
(setq ff (close ff))

Then this one:

(setq ff (open "C:\\test.txt" "a"))
(write-line "2nd line" ff)
(setq ff (close ff))

Now, may test again the first excerpt to see the difference.

This is what i was missing APPEND mode.

Thank You So Much Mircea.
