Question

How to run the bash scripts file?

  • Posted October 24, 2014

The following bash scripts can be executed one by one in my debian7 console.

apt-get update
apt-get -y upgrade
apt-get install -y build-essential  gcc  libtool  libxml2-dev libxslt1-dev  openssl  libssl-dev
wget https://www.python.org/ftp/python/3.4.0/Python-3.4.0.tgz
tar xf Python-3.4.0.tgz -C /usr/local/src/
cd /usr/local/src/Python-3.4.0/
./configure --prefix=/usr/local/python3.4  --with-ensurepip=install   
make 
make  install
ln -s /usr/local/python3.4/bin/python3.4   /usr/bin/python3.4

Why can’t be executed by the command bash -x /root/initial.sh when i save all the command in the file /root/initial.sh?

root@online:~# . /root/initial.sh

Somebody think that Windows line endings are different from Unix/Linux line endings. bash doesn’t know how to handle Windows line-endings. Create the file with an editor on Linux.

  1. i rewrite it in putty console with nano ,same problem remains. 2.It is strange that i nano the /root/ini.sh in putty console,there is just one line in it:
apt-get update

When i input :

sh /root/ini.sh 
E: Invalid operation update

There is no relationship betwwen my ini.sh and ‘\r’ ,what is the matter?

You might need to install the dos2unix package first:

sudo apt-get install dos2unix

run this, and try it again:

dos2unix /root/initial.sh

Maybe…

#!/bin/bash
 (apt-get update && apt-get -y upgrade && apt-get install -y build-essential  gcc  libtool  libxml2-dev libxslt1-dev  openssl  libssl-dev) > /dev/null
wget "https://www.python.org/ftp/python/3.4.0/Python-3.4.0.tgz"
tar "xf Python-3.4.0.tgz -C /usr/local/src/"
cd "/usr/local/src/Python-3.4.0/"
./configure --prefix=/usr/local/python3.4  --with-ensurepip=install   
make 
make  install
ln -s "/usr/local/python3.4/bin/python3.4"   "/usr/bin/python3.4"

It’s the line endings as someone else said. The errors you get about \r are definitely due to Windows line endings.

If you could use “pastebinit” to paste the exact content of those files to a pastebin maybe we can spot the mistakes.

think to kamaln7 , sudo apt-get install dos2unix dos2unix /root/initial.sh sh /root/initial.sh it is ok. But problem remains. 1.In gvim for windows i have set configuration in ~vimrc . set fileformat=unix when i save the file in gvim and sent it into my serverip, sh /root/initial.sh can not make it run. E: Invalid operation update and -bash: $‘\r’: command not found

  1. In notepad++ Edit -> EOL Conversion–unix format. same problem remain.

Is the transmission process cause the problem ? i change the window format with gvim or notepad++,but the transmission process change it from unix format into window format again?

My client system is win7, i have to work in win7 environment , it is inconvenient for me to change the file format with dos2unix mytarget.sh and then sh mytarget.sh . How can i solve the problem in gvim for windows and notepad++ ?
