I have a list of 350 rpms listed in a text file that are also installed in a cluster that is not online with the outside world. We have an internal yum repository. Is there a way to take the list, and download all the 350 installs for yum to bring back to the cluster? I hate thinking of downloading them one by one.
Thanks
reposync and making internal repos. (and then using kickstart) is better option, IMO.
But if you want to just download, then something as simple as:
yumdownloader $(cat myfile)
...might well do it. yumdownloader is in the yum-utils package. If you need to use yum/yum-downloadonly then you can do:
yum --installroot=/tmp/my-installroot --downloadonly install $(cat myfile)
...that will get you all the deps. too (not sure if that's what you want). If it doesn't fit on the command use yum shell:
perl -pe 's/^/install /' myfile > myfile-shell
echo run >> myfile-shell
yum --installroot=/tmp/my-installroot --downloadonly shell myfile
...but again, I think you really want to have usable repos. on your yum machines.
Try:
yum install `cat /path/to/pkgs_list`

I am new to using git. So i first install git from terminal using apt-get but then i remove it as in ubuntu the version is very old.
After this i install git from source code which i download from https://code.google.com/p/git-core/downloads/list. Then these are the commands used by me
sudo apt-get install libcurl4-gnutls-dev libexpat1-dev gettext libz-dev libssl-dev build-essential
tar -zxf git-1.9.0.tar.gz
cd git-1.9.0/
make prefix=/usr/local all
sudo make prefix=/usr/local install
Then when i put these commands it is behaving in this manner.
~/git-1.9.0$ which git
/usr/local/bin/git
~/git-1.9.0$ git --version
bash: /usr/bin/git: No such file or directory
Your shell remembers where it found the executable file for commands you run, to save itself the trouble (and you the delays) of hunting them down repeatedly. which isn't a bash builtin, so it doesn't know about that. When you've installed new code it's rarely a bad idea to
$ hash -r # reset the command-lookup hashtable
or if you've got just one particular command in mind,
$ hash -dcommand# forget wherecommandcame from
You might need to add /usr/local/bin/ to your $PATH, perhaps in ~/.bashrc; you might want to put it before /usr/bin/ there.
And you could simply type the entire path of the binary, e.g.
/usr/local/bin/git --version
or
/usr/local/bin/git status
You might try to use strace to understand what is going on.
Did you read git INSTALL file? You probably want to go the autoconf way (e.g. make configure first, then configure with appropriate arguments....) and you surely need to give relevant arguments at configure time, in particular --exec-prefix= and/or --libexecdir= ....
Many sites (including various SO articles) talk about using "rename" using Perl expressions to rename files.
This would be perfect, but apparently this is not the rename utility I have, and none of these articles seem to comprehend that there are multiple versions of "rename" and I can't seem to find where to get version that accepts Perl expressions.
How can I get my hands on the more powerful rename utility mentioned here, here, and here?
I'm running Fedora 20. My current rename command is from the util-linux package and apparently I need the Perl version, which is better.
I can only speak for Debian. The two programs are called
/usr/bin/rename.ul from the util-linux package (hence the .ul suffix)
/usr/bin/prename from the perl package
The actual rename command works via the /etc/alternatives mechanism, whereby
/usr/bin/rename is a symlink to /etc/alternatives/rename
/etc/alternatives/rename is a symlink to /usr/bin/prename
The same problem has been bugging me on Cygwin, which is a Red Hat product, so should be more similar to Fedora. I'll have a look on my company laptop on Monday. And I remember the Perl-rename having worked there sometimes. Probably before I installed util-linux.
If you install the Perl-rename to /usr/local/bin it will have precedence over rename from util-linux. Same goes for the manpage when installed to /usr/local/share/man/man1/.
I've just created a separate Perl-rename package on Github: https://github.com/subogero/rename
You can install it using cpan, which is the perl repository similar to pip for python.
Here is a tutorial on using cpan.
If you try to run rename it it looks like this
rename --help
call: rename from to files...
To install the perl rename you can do the following. You might need to install a few dependencies, you can generally just push enter
cpan
cpan1> install File::Rename
CPAN: Storable loaded ok (v2.20)
Going to read '/root/.cpan/Metadata'

That is how you would install the rename from cpan.
Next is to get it working on your system. As you might have more then one rename installed.
which rename
/usr/bin/rename
When you actually want this one.
/usr/local/bin/rename --help
Usage:
rename [ -h|-m|-V ] [ -v ] [ -n ] [ -f ] [ -e|-E *perlexpr*]*|*perlexpr*
[ *files* ]
Options:
-v, -verbose
Verbose: print names of files successfully renamed.
-n, -nono
No action: print names of files to be renamed, but don't rename.
-f, -force
Over write: allow existing files to be over-written.
-h, -help
Help: print SYNOPSIS and OPTIONS.
-m, -man
Manual: print manual page.
-V, -version
Version: show version number.
-e Expression: code to act on files name.
May be repeated to build up code (like "perl -e"). If no -e, the
first argument is used as code.
-E Statement: code to act on files name, as -e but terminated by
';'.
I just put it into /usr/bin/ but with a slight different name to make sure I did not break any existing scripts / programs the depend on the old one.
ln -s /usr/local/bin/rename /usr/bin/rename.pl
I had to do the following:
# In bash
sudo yum install perl-CPAN
sudo cpan
# In CPAN shell
install Module::Build
install File::Rename
On RedHat 8.4
sudo yum install perl-CPAN
sudo cpan
install module::Build
install File::Rename
than you can create an alias:
alias prename='/usr/local/bin/rename'
an use:
touch pic.jpeg
prename 's/\.jpeg$/.jpg/' *.jpeg
For Debian-family (.deb) distros, I recommend #SzG's answer.
For RedHat-family (.rpm) distros (e.g. Fedora), if your time is precious (like mine), you can download, compile, and install, from source via cpan in one, terse command:
# Install (replace `rename-1.9` below with another version if desired)
curl -L "http://search.cpan.org/CPAN/authors/id/P/PE/PEDERST/rename-1.9.tar.gz" | tar -xz && ( cd "rename-1.9"; perl "Makefile.PL"; make && make install )
# Cleanup
rm -rf "rename-1.9"
Note:
INSTALL_BASE can be set to modify the base installation directory.
e.g. perl "Makefile.PL" INSTALL_BASE=/usr/local
source
For Arch Linux, its
sudo pacman -S perl-rename
I created a post about Perl's rename for many distro:
https://unix.stackexchange.com/a/727288/12574
rpm based distros:
dnf install prename
archlinux:
pacman -S perl-rename
*BSD:
pkg install p5-File-Rename
Debian like/Ubuntu
apt install rename
slackware:
slackbuild
I recently had to install the glorious Perl rename package to Alpine Linux in a Docker container for a Gitlab CI/CD operation:
apk update
apk add --no-cache make perl-utils
cpan File::Rename
As the title is pretty clear (I hope so :) ), I'm looking for an easy way to install many softwares through apt-get command, I have created a shell script where I put all software I need but it's not very clean to do that I assume. The cleanest way is to tell apt-get to read into a file like the command pip.
Thanks in advance
Put the list of packages in a text file(say test.txt) with package names separated by spaces, like this -
python ruby foo bar
then you can just install with apt-get like this -
sudo apt-get install $(cat test.txt)
I recently tried to install monit on Ubuntu Natty from source. Here's my code:
apt-get -y install openssl libssl-dev bison flex
mkdir src && cd src
wget http://mmonit.com/monit/dist/monit-5.3.2.tar.gz
tar xzf monit-5.3.2.tar.gz
cd monit-5.3.2
./configure --prefix=/usr/local/monit
make && make install
However, when I install Monit using apt-get I am able to call monit directly from the command line using the keyword monit. I am not able to do so when I do the install from source. The same goes for PHP.
How can I enable this feature for when I install Monit (and other Linux programs) from source?
Thanks in advance.
EDIT
I was able to solve this by doing the following:
printf "\nPATH=/usr/local/monit/bin:\${PATH}\n" >> ~/.profile
source ~/.profile
This will apply for the currently logged in user (in my case root). To make it system-wide simply replace ~/.profile with /etc/profile.
So now I can can call monit (and any other program I install from source).
Using that command to install it will put it in /usr/local/monit, which won't be in your $PATH, as others have said. There are several options besides modifying your path, though. For instance, you can create a symbolic link from the real executable to one in your path. So if the executable is /usr/local/monit/monit, you can
ln -s /usr/local/monit/monit /usr/local/bin/monit
The advantage of creating the symbolic link is it will work for all users.
You can also create an alias, but that would only work for apps that run as you.
Edit your /etc/profile to add the path /usr/local/monit to the PATH variable.
For ex, if you earlier had this.
PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin"
You could change it to
PATH="/usr/local/monit:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin"
For example, if ./configure or Make tells me I'm lacking libX11.so.6, and it's nowhere on my system, is there a tool or website into which I could type
libX11.so.6
followed by a distribution/arch and get back
libx11-6
libx11-6-debug [or whatever; asking README would probably return reams of entries]
http://sysinf0.klabs.be/ does something similar for some distributions and architectures, but it doesn't seem to have more recent distributions. Also, they don't have an entry for the filename so you need to Google "packagename site:sysinf0.klabs.be".
I'm most interested in Ubuntu, but it would be good to know about similar tools for other distributions as well.
Debian does that via the website:
search the Packages page under Search contents of packages
the answer in this example
options selected where 'packages that contain files whose name contain the keyword' for the unstable distribution (as it is the largest) on 'any' architecture
Ubuntu probably does something similar but I don't know the website / launchpad that well.
You could also fetch the index file ftp://ftp.us.debian.org/debian/dists/sid/Contents-i386.gz but as it changes frequently the website option is probably more convenient.
$ sudo apt-get install apt-file
$ sudo apt-file update
$ apt-file search libX11.so.6
apt-file will let you list and search the contents of packages whether or not they are installed on your system.
$ sudo apt-get install auto-apt
$ sudo auto-apt update
$ sudo auto-apt updatedb
$ sudo auto-apt update-local
$ auto-apt run ./configure
For even more automation, auto-apt will detect attempts to access non-existent files and automatically prompt you to install the packages providing those files.
There is many other tools to do this
check this great page for this : http://www.debianhelp.co.uk/findfile.htm
It is for debian or Ubuntu
If you have a file on your machine, and you want to know which package is responsible for it, then (on Debian & Ubuntu) it's...
$ dpkg -S FILENAME
