Bash script to check if package(s) with number version exist in repo
Hi everybody,
I am on Archlinux, with a custom repository, and i am trying to do a little script to check if the package existing in the repository path.
So my problem in my while, is find the good regex to put in my condition to make it work with all packages
for i in $(pacman -Slq customrepo)
do
if [ -f /customrepo/$i-[0-9A-Za-z]*.pkg.tar.* ]
then
echo "$i exist"
else
echo "$i Don't !"
fi
doneFor exemple, after launch my complete script with bash -x, for "insync" i have this error message :
+ '[' -f /repository/insync-3.5.1.50115-1-x86_64.pkg.tar.zst /repository/insync-nemo-3.4.0.40973-1-any.pkg.tar.zst ']'
/home/powabanga/Documents/trucs/pkbuilds/kawacheck: line 3: [: /repository/insync-3.5.1.50115-1-x86_64.pkg.tar.zst: binary operator expectedDoes anybody can help me to find what should i writte to not have any errors ?

Re: Bash script to check if package(s) with number version exist in repo
This is definitely an X-Y problem - you have shown us how you are working on 'Y' but I can't even imagine what 'X' is. What is your end goal?
You're having pacman list all packages in the repo but explicitly telling it to not list version numbers ... then you are checking if each one of those exists with *any* version number? Well, of course they do.
Are you trying to find mismatches between the packages and/or versions in the repo db and the actual file content? If so, there are definitely better ways.
Do you wan to see which packages exist in a local cache with version numbers? If so, there are definitely better ways, e.g. ask pacman where it'd get the package (and check if they are http(s):// or file:// sources):
pacman -Slq customrepo | pacman -S --print -That said, the likely problem with your script is that you need to quote the variable ... that would likely avoid the shell error, but I still don't see how the whole thing would do anything useful.
You can throw a bit of sed at the output of the last command if you really want it formated in a not-so-useful way:
pacman -Slq customrepo | pacman -S --print - | sed "s|file:///var/cache/pacman/pkg/|Exists: |;s|http.*/os/x86_64/|Doesn't: |"But I suspect in reality you don't want to print "Exists" or "Doesn't" but instead just filter with grep for what you actually need, e.g instead of sed:
... | grep -v '^file:///'Last edited by Trilby (2021-08-19 14:27:29)

Re: Bash script to check if package(s) with number version exist in repo
hm...
in fact, there is two goals of this script :
(in my case the repository path is /repository , and the repository name is "kawa)
First : use it to build a table, with column who check "X" or "V" if the package exist in :
Build directory (path where i build all my packages with makepkg command
Repository database (does it exist in pacman -Sl custom repo command ?)
Repository path (if package is not in the folder with my customrepo.db, I will cannot install it with "pacman -S")
AUR repository (it can be useful to know if the package exist in aur or not )
Here is my full script :

Re: Bash script to check if package(s) with number version exist in repo
I'd *strongly* advise drastically simplifying that script at every level. Most notably, do not loop through every package, and do every check each time through the loop. Most (if not all) of those checks can be done as a single batch. Specifically for that last code box seems to loop through all possible entries and for each one it does an ls, grep, wc, then another for loop dependening on the output of that. This could result in thousands of processes when only a few are necessary. I have no idea what that sed is for after pacman -Slq: package names can't have spaces, so the sed is a no-op. But in addition to that, there's no reason to get the list of packages from the repo: the goal seems to be to remove all but the most recent version of each package in REPOPATH.
The below is a good start at doing that without the loops. I've left out the deletion as you should check the results first - but this should give the list of deletion candidates. No loops, and just three processes regardless of how many packages are in the repo.
find $REPOPATH -maxdepth 1 -printf %f\\n | sort -rV | awk '$1 == lastpkg; { lastpkg = $1; }'Actually, I wouldn't be surprised if there weren't pacman or pacman-contrib tools to do this too - but I've never maintained my own repo - but certainly loops within loops with countless commands are not necessary. And all that unnecessry code makes troubleshooting very difficult. Simplify first.
EDIT: And now I've just realized this is *exactly* what paccache does: use that instead!
