[SOLVED] Text Above and Bellow Selected Lines

blueray · 02-24-2020, 01:30 AM

I am using Geany.

These is a option Edit > Format > Send Selected To > Set Custom Commands

Here, for example if I want to sort selected text, I just use sort command.

What I want this (Set Custom Commands) to do is put "...." above and bellow my selected line/s.

For Example if I select the following lines,

Code:

touch sample_file.txt
ls
rm sample_file.txt
ls

Then go to Edit > Format > Send Selected To > MyCommand

I am expecting to get

Code:

....
touch sample_file.txt
ls
rm sample_file.txt
ls
....

Is there any way I can achieve this?

Try setting this command

Code:

sed '1 s/^/....\n/; $ s/$/\n..../'

You could use awk's BEGIN/END for this.

Code:

$ cat 4175670153.txt | awk 'BEGIN {print "...."} {print $0} END {print "...."}'
....
touch sample_file.txt
ls
rm sample_file.txt
ls
....

Thank you very much.

Code:

sed '1 s/^/....\n/; $ s/$/\n..../'

or,

Code:

awk 'BEGIN {print "...."} {print $0} END {print "...."}'

Both Works.

Few more solutions that worked for me:

Code:

echo -e "....\n$(</dev/stdin)\n...."

or,

Code:

 cat <(printf "....\n") - <(printf "....\n")

or,

Code:

echo "....";cat -;echo "....";

The last one is not fully tested though.
