I've perl version 5.22.0 but I need to downgrade it to 5.12.4. is it possible in linux system ?
I found the perlbrew and install it in Red Hat 6 bash shell but I need to use it in c shell. Is it possible to run perlbrew in C shell ?
Thank you,
Yes, it's possible to install 5.12.4 on your system (without or without perlbrew).
Yes, perlbrew is compatible with csh.
If you already have perlbrew installed, just add the following to your login script:
source ~/perl5/perlbrew/etc/cshrc

I am using Windows 10 in my machine, and currently installed git bash on it.
I wanted to install node and npm for my application.
when i tried :
apt-get install nodejs
"apt-get" command not found,
I tried google and got
sudo install nodejs
"sudo" command not found.
How to use sudo and apt-get command on my git bash.
Git for Windows comes with a Windows port of Bash and a collection of few more common *nix command-line tools that have been compiled for Windows, it does not provide a complete *nix environment. Hence you cannot use tools like sudo and apt-get which modify the *nix operating system.
However, there are other tools, programs if you like, available.
Try to install node " the windows way ".
win-sudo package adds sudo to windows.
kafaior at Super User suggests:
A working sudo replacement for Cygwin's mintty terminal would be to place the following script in user's PATH:
$!/bin/bash
cygstart --action=runas mintty -e `which bash` -lc \"$#\"
Maximus mentions how to add sudo (well, csudo) via cmder.
Super User has a similar question here.
It looks like there is a command runas or elevate commands. These might be for PowerShell, rather than git bash. I'm not sure.
I found your this while looking for a way to add rsync to Git Bash. So below I included info that may or may not work for sudo or apt-get. If they do not work directly for specific commands the OP is asking about, they may inspire a solution that does work. Also this could help others who arrived here as I did.
rsync is another unix command not available in the standard installation of git bash.
However, you can download and install the Git for Windows SDK (scroll to the bottom of the page for the link). This will allow you to create a version of the Git for Windows installer that does include additional *nx commands.
Install the Git for Windows SDK according to the instructions. Part 2 is where you add the packages you want, that aren't included in the standard git bash installation. Part 3 is where you create a Git installer, which will include the additional packages. If you skipped step 2, this should produce an installer similar to the standard installer.. There is a good discussion as to why they cannot include these commands in the general distribution.
It is also possible to just grab rsync filehere or here and unpack it directly within your Git installation, and it works. I dunno if it is also possible to do something similar for sudo or apt-get.
Finally, it looks like there is a way to get *nix commands available within the Git Bash shell via cmder. Here are the instructions.
Installing applications in git bash does not sound right to me. I would suggest you either use the native Windows installer (https://nodejs.org/) or, if you prefer a package manager, use Chocolatey (https://chocolatey.org/) to install nodejs with:
choco install nodejs
I am use Ubuntu 14.04 LTS with Perl 5 (v5.18.2), but for new versions of rxvt and surf I need Perl v5.20+.
As solution I found perlbrew and install Perl v5.20, found .deb with rxvt, but anyway cannot install, because it use system Perl.
My question is how to install applications on Linux with Perl dependency and do not break internal compatibility of Linux Core?
for new versions of rxvt and surf I need Perl v5.20+.
That's not true.
rxvt 2.7.10 uses a Perl script will work even with 15 year-old 5.6.
surf 1.0.6 doesn't use Perl at all (assuming you mean this project).
Were you to try to install these from source, it wouldn't matter at all what Perl you had available.
Instead, you appear to be trying to install packages built for a system other than yours. To install the rxvt and surf packages you have, you need to have version 5.20 of the distributor's perl package. No matter how many version of perl you install, you'll never satisfy that requirement.
You can't install those packages. You'll need packages appropriate for your system, or you'll need to install the libraries from source.
I am new to Linux (new as in installed it yesterday), I need it for my programming course in the university and I've been told to install specific versions of specific programs, but though I've used apt-get install to install them (having previously done apt-get update) they aren't in the correct version.
The programs that I need are make 4.0 and valgrind 3.10.1.
apt-get installs make 3.81 and valgrind 3.10.0.SVN.
I have tried typing "apt-get install make4.0" and "apt-get install valgrind10.3.1" to no avail. I have downloaded them from the internet and followed what instructions I could understand to install the newer versions but it keeps saying that I have the older ones. (I'm not sure if I can post direct links here, if I can let me know and I'll post where I got them from).
What have I been doing wrong? How can I fix this?
I am currently running Linux Mint.
Thanks for any answer in advance.
Due to a long-standing unresolved Debian bug report, GNU Make remained the age-old 3.81 in Debian for a very long time, and as a consequence, in Debian-based distributions such as Ubuntu and Mint.
The latest Debian release, Jessie, has upgraded to 4.0, so Debian-based distributions will have that upgrade. However, it is better to use 4.1.
This has been discussed many times on the GNU Make mailing list and elsewhere.
So to get a newer version, you must compile it from scratch.
This is easy:
Install the required packages (gcc, make and such).
Open up a shell (if you're using the GUI, a terminal window).
Type the following commands (or something equivalent, e.g. you can use curl instead of wget):
cd /tmp
wget http://ftp.gnu.org/gnu/make/make-4.1.tar.gz
tar xvf make-4.1.tar.gz
cd make-4.1/
./configure
make
sudo make install
cd ..
rm -rf make-4.1.tar.gz make-4.1
Now, make 4.1 is in /usr/local/bin/make.
You can verify it is there with whereis make.
You can make it your default make by prefixing /usr/local/bin to your $PATH variable in your shell startup file; for instance, in .profile or .bashrc if you use the bash shell.
Don't try to install a self-compiled make (or anything else that doesn't come from the distribution's package manager) into /bin or /usr/bin; doing that will confuse your package manager.

How to check for all installed versions of perl?
As Sobrique suggested in comments, you should never touch system perl. I'd suggest using perlbrew. With perlbrew you can install different versions of perl from local user, and to check all installed versions of perl using perlbrew just do $ perlbrew -l.
how to switch between them while executing a program?
Install multiple perls
$ perlbrew -v install perl-5.20.0
$ perlbrew -v install perl-5.13.4
Switch between them
$ perlbrew switch perl-5.20.0
$ perlbrew switch perl-5.13.4

I am trying to configure apache thrift and i have installed cygwin to be able run the bash scripts on windows and i have installed libtool package as well and i still seem to be getting an error message:
couldn't find libtoolize!
I have also tried this in the DOS prompt and the bash shell as well, although you cant un bash scripts in the DOS window.
When I run a bash script. I would like some help with this please as I'm really interested in using the apache thrift platform.
'libtoolize' is a part of libtool.
You can dowload latest version of libtool from http://ftp.gnu.org/gnu/libtool/, extract it, then run ./configure and make install from cygwin terminal.
This worked for me.
