[SOLVED] How to remove dashes from the end of lines in a file

Issue

macOS. I'm trying to remove all dashes - from the end of lines in a file but I've not been able to do so. I've tried following commands so far and none worked

sed -e 's/^-//' -e 's/-$//' output.txt
cat output.txt | tr -d -
tr -d '[0-9-]' < output.txt
sed 's/[0-9-]//g' output.txt > output1.txt

Content of my file output.txt just for example

asfdsfds-
asdfdf-
sdfdes dsfds dsfds-

Solution

If your only requirement is indeed to remove all dashes from such input file, a single sed such as below would be enough :

➜  ~ cat output.txt
asfdsfds-
asdfdf-
sdfdes dsfds dsfds-

➜  ~ sed -i '' 's/-//g' output.txt

➜  ~ cat output.txt
asfdsfds
asdfdf
sdfdes dsfds dsfds
➜  ~
