First off, great tutorial and examples. Found exactly what I was needing.

Can anyone explain to me what the difference is between the ` and ‘ characters. For example, in comment 3109 by thelinuxblog.com they suggested:

NAME=`echo $VAR | cut -d \. -f 1`

I previously had tried wrapping it with the single quote character, which just treated the statement as a string. Can anyone shed some light on the significance of the ` character?

Thanks!

Brilliant. You made it quick, simple, and easy.
If only all tutorials could be this way. ;)
Thanks!

@yaker agreed, I'd like to see the last option, the first is always easy since it should be "1". To get the last field, you'd have to count the number of fields and specify that, or reverse the string and use cut to get the first (which was last) again. like: cat test.txt | rev | cut -d , -f 1

it will be more comfortable if the “-f” param can accept fields such as “first/last”

Hey Maga, assuming the filename in VAR doesn’t have any periods in it you can use:

NAME=`echo $VAR | cut -d \. -f 1`

Here is another way subtracting 5 characters (extension + blankspace) from the $VAR and using the character cut:
echo $VAR | cut -c -$((`echo $VAR| wc -c` – 5))

However, there are probably better ways of doing it.

oops, I forgot to say that I want to store the output in a variable, which was my question….

so I’ve tried:

name=echo “${files[$i]}”| cut -d ‘.’ -f 1

and I don’t get anything stored in the variable….

Awesome tutorial on cut!!! Now it’s part of my bookmarks… :)

I still have one question… I have the name of a file stored in a variable and want to get only the name, not the extension…
I’ve tried
echo ${files[$i]}| cut -d ‘.’ -f 1 and it doesn’t work…

could anyone tell me what am missing here?

thx!!
