pipes, dpkg and default screen width (sort of)

[charlie derr]

Hi,
Often I find myself executing the following:
$ dpkg -l '*foo*'

to find all packages with foo in the name.
When instead I look for only installed foo packages as follows:
$ dpkg -l '*foo*' | grep ii

the output is truncated, and if there's a foo package with a
particularly long package name, I won't see the full name.
Is there an envrironment variable I could set to prevent this?
Or some other workaround simpler than redirecting the first
command to a temporary file (and then using grep on that)?
thank you so much in advance,
~c

Yes, you can use the COLUMNS variable for this.


Yours sincerely
