SED "No such file or directory"
Your script was saved using CR+LF (Windows) line endings. The shell does not understand those – it uses only LF as the line ending marker, and the CR becomes part of the command. Thus:
- Your logs are being written to the file
UbuntuSetupLog.txt<CR>
. (Unfortunately both CR and LF are allowed in file names...) - Your sed commands are trying to edit the file
/etc/ssh/sshd_config<CR>
, and the CR byte mangles the error message when it's being printed (acting as an actual carriage return).
Use dos2unix
or frodos
to convert the script. Or if you prefer:
sed -i 's/\r$//' myscript.sh

So, I am an intermediate linux user, I have just discovered sed and want to use it to automate some configuration during my usual install/configure script.
I have scrolled through all of the forums to locate an issue similar to mine, however I have not seen many using the same format as I am and I am not sure why. I came to the script I have below through looking at a number of other sed scripts and using the ones that worked with what I am trying to do. Then I put it in a script and it throws the error.
I am unable to locate the issue in this sed script:
sudo sed -i 's/#AllowTcpForwarding yes/AllowTcpForwarding no/g' "/etc/ssh/sshd_config" sudo sed -i 's/#PermitRootLogin yes/PermitRootLogin no/g' "/etc/ssh/sshd_config" sudo sed -i 's/X11Forwarding yes/#X11Forwarding yes/g' "/etc/ssh/sshd_config" sudo sed -i 's/#StrictModes yes/StrictModes yes/g' "/etc/ssh/sshd_config" sudo sed -i 's/#IgnoreRhosts yes/IgnoreRhosts yes/g' "/etc/ssh/sshd_config" sudo sed -i 's/#HostbasedAuthentication no/HostbasedAuthentication no/g' "/etc/ssh/sshd_config" sudo sed -i 's/#RhostsRSAAuthentication no/RhostsRSAAuthentication no/g' "/etc/ssh/sshd_config"
I have also written the command like:
sudo sed -i 's/#AllowTcpForwarding yes/AllowTcpForwarding no/g;s/#PermitRootLogin yes/PermitRootLogin no/g;s/X11Forwarding yes/#X11Forwarding yes/g;s/#StrictModes yes/StrictModes yes/g;s/#IgnoreRhosts yes/IgnoreRhosts yes/g;s/#HostbasedAuthentication no/HostbasedAuthentication no/g;s/#RhostsRSAAuthentication no/RhostsRSAAuthentication no/g' "/etc/ssh/sshd_config"
I get the same error:
: No such file or directoryhd_config
On both when run in a script with other arguments that all complete with no issues. I can run both of the commands successfully by themselves.
The full script is:
#!/bin/bash # Title: Ubuntu Setup # Author: Matthew Williams # Date: 10/31/2016 echo "***Ubuntu Setup Script Log***" `date +%d%m%Y_%H:%M.%S` | tee UbuntuSetupLog.txt sudo apt-get install -y libpcsclite1 pcscd pcsc-tools libssl-dev libpam0g-dev pkg-config libpcsclite-dev gdebi opensc unity-tweak-tool gnome-do openssh-server openssh-client byobu | tee -a UbuntuSetupLog.txt echo "***Files Installed***" `date +%d%m%Y_%H:%M.%S` | tee -a UbuntuSetupLog.txt # # Configure Networking / SSH # echo "***Configuring Networking/SSH***" | tee -a UbuntuSetupLog.txt # sudo sed -i 's/#AllowTcpForwarding yes/AllowTcpForwarding no/g;s/#PermitRootLogin yes/PermitRootLogin no/g;s/X11Forwarding yes/#X11Forwarding yes/g;s/#StrictModes yes/StrictModes yes/g;s/#IgnoreRhosts yes/IgnoreRhosts yes/g;s/#HostbasedAuthentication no/HostbasedAuthentication no/g;s/#RhostsRSAAuthentication no/RhostsRSAAuthentication no/g' "/etc/ssh/sshd_config" sudo service sshd restart 2>&1 | tee -a UbuntuSetupLog.txt # echo "***Configuring Networking/SSH Complete***" `date +%d%m%Y_%H:%M.%S` | tee -a UbuntuSetupLog.txt # echo "***Script Complete***"

I need this script to automate a number of other machines. I know there are better methods and everyone has their own favorite way to to it. My only question is what am I doing wrong in sed? I am unsure what I need to do to change this script and I have been looking online fruitlessly for about a week.
I believe the error is in the way I am calling the file but not sure how else to do it.

Matthew Williams over 7 yearsThis was the issue, I thank you for locating my stupid mistake. I was coding this in Notepad++ on a different machine than my normal one. I forgot to do the EOL Conversion since I was on a windows machine at the time. For those that need that setting. It is located in Edit>EOL Conversion.

Admin almost 2 yearsSame issue on my end, spent an hour trying to figure it out. Was creating sh scripts in VSCode on Windows and uploading them to a linux based container. One clue was that they show up as
^M
characters invi
editor on linux. Fixed by selectingLF
in VSCode footer menu, instead of the defaultCRLF
