Closed 4 years ago.I'm using following script on linux server. And which is giving:: not found No such file or directoryThis is the script: # -# K.Sugunan Host health check# Description## This script to initiate health check on servers.# It will check for CPU, memory and some connectivity with# up stream and down stream system.## -# Applying initial variables and loading config parametersDOCROOT=$(pwd)'/'TIMENOW=$(date +'%Y-%m-%d%H:%M:%S')echo $DOCROOT.
$DOCROOT'config/telnet.sh'echo $CPUAThe error will be like follows:: not found No such file or directory: not found No such file or directory/home/sugunan/phobos/: not found No such file or directory: cannot open No such file or directoryos/I use following ways to run the script ksh poc.shsh poc.sh./poc.shAll of the above giving similar error. Even I include #!/bin/bash still the error exist. I have tried #!/bin/ksh and #!/usr/bin/ksh also. All of that gives the error. What may be the reason for the issue on this server? It appears like the empty lines contain an invisible (unprintable) character, and the server is trying to run it as if it were the name of a command; hence the error: not found No such file or directory. Delete the empty lines or ensure they're really empty.Edit: OP's comment confirms that it is indeed the case, as the code was written under Windows.
On Windows, ASCII text files end each line with a Line Feed + Carriage Return character, while UNIX uses only a Line Feed.To solve this, you can either:. copy & paste the code directly on an editor under Linux. make sure you set your Windows editor to convert end-of-line characters to the UNIX standard. use the dos2unix command to convert the Windows ASCII file to a UNIX one.
Sh is a unique subprocess wrapper that maps your system programs to Pythonfunctions dynamically. Sh helps you write shell scripts in Python by giving youthe good features of Bash (easy command calling, easy piping) with all the powerand flexibility of Python.
Starting with sh sh is a full-fledged subprocess interface for Python that allows you to call anyprogram as if it were a function. Sh lets you call just about anything that youcould run from a login shell much more neatly than you can with subprocess.Popen,and more importantly lets you capture and parse the output much more readily.Installation The installation of sh is done through the pip command$ pip install shUsage The easiest way to get up and running is to import sh directly or import yourprogram from sh. Every command you want to run is imported like any other module.That command is then usable just like a Python statement.Arguments are passed per usual, and output can be captured and worked with in alike fashion.# get interface informationimport shprint sh.ifconfig('eth0')from sh import ifconfigprint ifconfig('eth0')# print the contents of this directoryprint ls('-l')# substitute the dash for an underscore for commands that have dashes in their namessh.googlechrome('Commands with sh Commands are called just like functions.'

Note that these aren't Python functions, these are running the binary commandson your system dynamically by resolving your PATH, much like Bash does. In thisway, all the programs on your system are easily available in Python.' Many programs have their own command subsets, like git (branch, checkout).sh handles subcommands through attribute access.from sh import git# resolves to 'git branch -v'print(git.branch('-v'))print(git('branch', '-v')) # the same commandKeyword Arguments Keyword arguments also work like you'd expect: they get replaced with thelong-form and short-form commandline option.
