I have to often make changes to configuration files such as httpd.conf and squid.conf. These files have a large number of lines that are commented out, mostly comments and some possible configuration directives that have been commented out as they are not required by default. A problem I face while editing such files is that there are so many lines commented out that I need to scroll down many lines before I can find the next active configuration directive. I found a fine solution to help me out with this.<\/p>\n
I now use the following command when I want to just look at the active directives in the Apache configuration file:<\/p>\n
# sed \u2018\/ *#\/d; \/^ *$\/d\u2019 \/etc\/httpd\/conf\/httpd.conf<\/p>\n
This command reads the file \/etc\/httpd\/conf\/httpd.conf and filters out all the comments and extra white spaces, leaving just the active configuration settings. This makes it very easy for me to look at the configuration file.<\/p>\n
If you want to just filter out the lines that begin with comments run the following command:<\/p>\n
# sed \u2018\/ ^#\/d; \/^ *$\/d\u2019 \/etc\/httpd\/conf\/httpd.conf<\/p>\n
It\u2019s pretty much the same command as earlier with a small change. The first * is replaced by ^, which is regex for beginning of line.<\/p>\n","protected":false},"excerpt":{"rendered":"
