I have installed WSL Ubuntu 20.04 on windows 11. I am trying to run the following File:
echo "Delete Lines that contain Given Word: "
echo "Before Deletion: "
cat "$1"
sed -i.bak "/$2/d" "$1"
echo " "
echo "After Deletion: "
cat "$1"
This code deletes all lines in a given text file that contain a given word. The command line argument I am giving in terminal is:
bash delfile.sh test.txt I
where delfile.sh is the shell script, test.txt is the text document and "I" is the word that gets its entire line deleted.
The text in test.txt is:
Hello Friend!
My Good Name Is
Johnny Jack.
I come from the
planet Earth
and I live in Italy.
I like Pasta.
Everytime I run the code, I get the following output:
Delete Lines that contain Given Word:
Before Deletion:
cat: 'test.txt'$'\r': No such file or directory
: No such file or directory
After Deletion:
Hello Friend!
My Good Name Is
Johnny Jack.
I come from the
planet Earth
and I live in Italy.
I like Pasta.
As you can see, the last cat $1 is able to print the contents of the file, but the first cat and sed commands give error "No such file or directory" even though all files are in same folder.
I tried running this same setup on a different system and it works fine there, but just not on the one I use frequently. I tried
sed -i 's/\r//' text.txt
to convert ASCII text, with CRLF line terminators to just ASCII text, but that also didn't work. All solutions I found on the internet indicate that the problem is something related to how windows and linux handle endline differently, but seeing as this code runs perfectly fine on a different system, and that the last cat command also works, I doubt that that is the case.
If the shell file simply contains sed -i.bak "/$2/d" "$1" then my file gets edited and the lines containing "I" get deleted, but as soon as another cat $1 comes, the last one is executed and the ones above give error.
If anyone can help sort out this issue, it will be much appreciated.

Reset to default 0Most likely, you shell script has CR or spaces in the command that is failing (the first cat)
Open you script with "vi" - and do "set list".
