SMB Not Able to Use Date Command Substitution

Question

smbclient //10.10.101.29/it -W WORKGROUP -U user --password pass -c 'put ./file_$(date +%Y_%m_%d).file ./folder/file_$(date +%Y_%m_%d).file'

The above does not work & gives me an error stating: ./file_$(date does not exist

I have tried variables:

date=$(date +%Y_%m_%d)

This results in the same behavior, but instead I get the following message: ./file$_{date}.file does not exist

Is it not possible to use the variables from the Ubuntu shell in the smb command or smb subshell? Are there any alternatives?

Answer 1

It should work with double quotes like

smbclient //10.10.101.29/it -W WORKGROUP -U user --password pass -c "put file_$(date +%Y_%m_%d).file"

or

date=$(date +%Y_%m_%d)
smbclient //10.10.101.29/it -W WORKGROUP -U user --password pass -c "put file_${date}.file"
