``dpkg -l'' on its own in a terminal produces wide output, e.g.:
$ dpkg -l perl* Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-===================================-===================================-====================================================================================== ii perl 5.8.3-3 Larry Wall's Practical Extraction and Report Language. ....
but when I send its output to a pipe or a file, I get narrow output:
$ dpkg -l perl* |head Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii perl 5.8.3-3 Larry Wall's Practical Extraction and Report ....
I want to dump a complete list of installed packages to a file as part of my backup procedure. man dpkg-query suggests using --showformat=format, in particular: "Package information can be included by inserting variable references to package fields using the ${var[;width]} syntax." But it doesn't say what the variable
names are. Suggestions?
Thanks, Adam
How about dpkg --get-selections
