Shell Programming and Scripting

Code:

echo  "1.1    Apply latest OS patches;"  
awk '/1.2 Install/ {P=0} P {print $0} FNR==1{printf("From file %s:\n", FILENAME)} /1.1 Apply/ {P=1}' solarisappsummary.txt solarisdbsummary.txt solaris_websummary.txt 
echo "1.2    Install TCP Wrappers;"    
awk '/1.3 Install/ {P=0} P {print $0} FNR==1{printf("From file %s:\n", FILENAME)} /1.2 Install/ {P=1}' solarisappsummary.txt solarisdbsummary.txt solaris_websummary.txt

Why is the error on the title showing up?

As has been suggested in some of your threads before, UNIX utilities expect lines to be terminated by a <newline> character; not a <carriage-return><newline> character pair! Get rid of the <carriage-return> characters at the ends of the lines in your shell script and your script will stand a chance of being able to process files named solaris_websummary.txt instead of failing when it tries to find a file named solaris_websummary.txt<carriage-return>.

AND PLEASE, be careful when showing us diagnostic messages produced by your code. You should never see a message about a filename starting with a capital letter when the filenames in your script do not contain any capital letters. Although diagnostic message output can vary from system to system, with the code you showed us, we would expect diagnostics more like:

Code:

'wk: can't open file 'solaris_websummary.txt
