I have a format string that is generally of the format:
PRODUCT_NAME-VERSION-OS(-INSTALLER)?.SUFFIX
I want to delete just the VERSION
part of it. VERSION
is defined as something matching: [0-9]+\\.[0-9]+\\.[0-9]+
. Therefore I want to do something like: echo NAME | sed -i "\\-/[0-9]+\\.[0-9]+\\.[0-9]+/d
echo NAME | sed -i "\\-/[0-9]+\\.[0-9]+\\.[0-9]+/d
so that I get PRODUCT_NAME-OS(-INSTALLER)?.SUFFIX
.
How do I do that?
Eg
sed
deletion operates over the matched line. So, in your exammple, you'd be deleting the entire line. You should head for substitutions instead. Take a look at the examples below:
$ sed -E 's/(.*)-[0-9]+\.[0-9]+\.[0-9]+(.*)/\1\2/'
<<< "Dropbox-1.0.0-win32-setup.exe"
Dropbox-win32-setup.exe
$ sed -E 's/(.*)-[0-9]+\.[0-9]+\.[0-9]+(.*)/\1\2/'
<<< "gdrive-2.32.1-linux.deb"
gdrive-linux.deb
$ sed -E 's/(.*)-[0-9]+\.[0-9]+\.[0-9]+(.*)/\1\2/'
<<< "azure-92.0.3-mac-osx"
azure-mac-osx
Just remove all from first -
to second -
cat file
PRODUCT_NAME-VERSION-OS-INSTALLER.SUFFIX
PRODUCT_NAME-VERSION-OS.SUFFIX
Dropbox-1.0.0-win32-setup.exe
gdrive-2.32.1-linux.deb
azure-92.0.3-mac-osx
sed 's/-.*-/-/' file
PRODUCT_NAME-INSTALLER.SUFFIX
PRODUCT_NAME-OS.SUFFIX
Dropbox-setup.exe
gdrive-linux.deb
azure-osx
