Breaking lines which contains more than 50 characters in a file
Hi,

I have a file which contains many lines. Some of them are longer than 50 chars. I want to break those lines but I don't want to break words, e.g. the file
Code:
This is an exemplary text which should be broken aaaaaa bbbbb ccccc
This is the second line
This line should also be broken aaaaaaaaaaaaaaaaaaaaaa

Should be changed in this way:
Code:
This is an exemplary text which should be broken
aaaaaa bbbbb ccccc
This is the second line
This line should also be broken
aaaaaaaaaaaaaaaaaaaaaa

Thanks in advance

Have a look at the man page of "fmt". "fmt -50" is probably what you want.

I hope this helps.
