in Categories File-management, Script last updated November 27, 2019

Here is a handy and useful Linux and Unix shell script that reduce PDF file size using Ghostscript. No need to upload your PDF file to the shady third-party website. Just do it from the terminal. I tested it with both CentOS and Ubuntu/Debian Linux.

Shell / sed Program To Remove All C and C++ Comments From Program File

in Categories Academic, Script last updated May 6, 2008

Write the shell / sed program which remove all the comments from a simple C program stored in your current directory. You can assume that the c source code contains only syntactically correct comments:
+ start with // and end with a newline

+ starting with /* and ending */ (can be multiline)

+ nesting of comments is not allowed

Make sure that C source is not changed at all.

How do I use this sed script?

$ ./script.sed < input.c $ ./script.sed < input.c > output.c
$ for c in *.c; do script.sed < $c > /tmp/zyzcc.c; /bin/cp -f /tmp/zyzcc.c $c; done

Sample sed code to remove all comments from sed

Please note that this program is copied from public domain.
