Windows – How to get ec2 command run in git-bash

amazon ec2command linegit-bashwindows 7

I installed ec2 command line tools on windows this morning. When I try to run a command ec2-describe-instances in the git bash, I get this output:

Exception in thread "main" java.lang.NoClassDefFoundError: com/amazon/aes/webservices/client/cmd/DescribeInstances
Caused by: java.lang.ClassNotFoundException: 
com.amazon.aes.webservices.client.cmd.DescribeInstances
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
    at java.security.AccessController.doPrivileged(Native Method)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: com.amazon.aes.webservices.client.cmd.DescribeInstances. 
Program will exit.

But if I open up just standard cmd, everything works fine. I want to be able to use my git bash for everything. I noticed that the git bash just uses the cmd prompt but with extra options. The shortcut for the git bash has this in the target:

C:\Windows\System32\cmd.exe /c ""C:\Program Files\Git\bin\sh.exe" –login -i"

How can I get ec2 command line tools running in the git bash?

Best Answer

I found a solution here: bash shell does not run .bat files

Run

cmd.exe '/c filename.batorexe'

in the appropriate directory (you can't do a subfolder for some reason).

Linux – Split PDF document from command line in Linux

I find pdfseparate very convenient to split ranges into individual pages. This command would extract pages 1 - 5 of input.pdf into files named output-page1.pdf, output-page2.pdf, ...

pdfseparate -f 1 -l 5 input.pdf output-page%d.pdf

If you want to recombine them into page ranges, for example pages 1-3 in one document and pages 4-5 in another, you can use the companion program, pdfunite, as follows:

pdfunite output-page1.pdf output-page2.pdf output-page3.pdf final-pages1-3.pdf
pdfunite output-page4.pdf output-page5.pdf final-pages4-5.pdf

I believe theese tools are part of poppler and may already be installed on your system.

Windows – How to configure git bash to display a timestamp for each command

This is solution to your problem, only difference from what you wrote, is that timestamp is displayed after the command output, and not before.

Under the Windows Program Files folder, open Git\etc\profile or Git\etc\profile.d\git-prompt.sh, search for lines which look like:

PS1="$PS1"'\n'                 # new line
PS1="$PS1"'\[\033[32m\]'       # change color
PS1="$PS1"'\u@\h '             # user@host<space>
PS1="$PS1"'\[\033[33m\]'       # change color
PS1="$PS1"'\w'                 # current working directory
if test -z "$WINELOADERNOEXEC"
then
    PS1="$PS1"'$(__git_ps1)'   # bash function
fi
PS1="$PS1"'\[\033[0m\]'        # change color
PS1="$PS1"'\n'                 # new line
PS1="$PS1"'$ '                 # prompt: always $

And add line

PS1="$PS1"' \t'                # time

before second-to-last line. That will give you prompt like:

user.name@machine /c/somedirectory 18:34:35
$ git pull origin develop
remote: Counting objects: 1, done.

user.name@machine /c/somedirectory 18:42:12
$
