I have a problem thatI can not solve even after scanning the Web. I trust in your help.

I have a text file that contains several strings of different lengths.

https: //insidemiamitatto.com/gugwywgifuw '";
https://insidemiamitatto.com/gugyiwyeiuiuweyiweyi '";
https://insidemiamitatto.com/gugyiipi9uuuppopi '";

I need to eliminate with Applescript or Terminal the last 3 characters, i.ee '";

I tried it with sed, but my invocation eliminates the characters only from the longer strings, leaving the others with 3 characters.

Is there a way to eliminate the final 3 characters in each string?


I also have a second question:

Always with sed I can remove strings e.g:

sed -i.bak -e '1,200d; 1874,2842d'

This virtually eliminates a part of the initial and final text.

In the rest of the files, I string groups that alternate every 18 strings, and I would like to erase 17 in each group, for example:

1-18 19-37 38-55.

I would keep the strings 1 19 38.

Is sed or other feasible? I am using BBEdit, but every time I have to count manually, and it is exhausting when editing many files.

To delete last 3 characters of each line:

sed -e 's/...$//'

For the second part:

$ echo "1-18 19-37 38-55" | sed -E 's/([0-9]+)-[0-9]+ ?/\1 /g'

1 19 38

  • Can you edit your question to include that additional information? People coming to this page won't necessarily look at all the past "answers" to find information they need to answer the question. – John N Dec 15 '16 at 9:43
