ccat<\/strong>\u00a0is command line similar to\u00a0cat command<\/a>\u00a0in Linux that displays the content of a file with syntax highlighting for the following programming languages:\u00a0Javascript<\/strong>,\u00a0Java<\/strong>,\u00a0Go<\/strong>,\u00a0Ruby<\/strong>,\u00a0C<\/strong>,\u00a0Python<\/strong>\u00a0and\u00a0Json<\/strong>.<\/p>\n

To install\u00a0ccat<\/strong>\u00a0utility in your Linux distribution, first assure that the\u00a0wget utility<\/a>\u00a0is present in your system. If the\u00a0wget command<\/a>\u00a0line is not installed in the system, issue the below command to install it:<\/p>\n

# yum install wget        [On CentOS\/RHEL\/Fedora]\r\n# apt-get install wget    [On Debian and Ubuntu]\r\n<\/pre>\n
In order to install the latest version of\u00a0ccat<\/strong>\u00a0command line via the latest compiled binaries, first download the compressed tarball by issuing the below command. The binary and source code releases archives can be found at the official\u00a0ccat github webpage<\/a>.<\/p>\n
-------------- On 64-Bit --------------<\/strong> \r\n# wget https:\/\/github.com\/jingweno\/ccat\/releases\/download\/v1.1.0\/linux-amd64-1.1.0.tar.gz \r\n\r\n-------------- On 32-Bit --------------<\/strong> \r\n# wget https:\/\/github.com\/jingweno\/ccat\/releases\/download\/v1.1.0\/linux-386-1.1.0.tar.gz \r\n<\/pre>\n
After archive download completes, list the current working directory to show the files, extract the\u00a0ccat tarball<\/strong>(the\u00a0linux-amd64-1.x.x<\/strong>\u00a0Tarball file) and copy the\u00a0ccat<\/strong>\u00a0executable binary from the extracted tarball into a Linux executable system path, such as\u00a0\/usr\/local\/bin\/<\/strong>\u00a0path, by issuing the below commands.<\/p>\n
# ls\r\n# tar xfz linux-amd64-1.1.0.tar.gz \r\n# ls linux-amd64-1.1.0\r\n# cp linux-amd64-1.1.0\/ccat \/usr\/local\/bin\/\r\n# ls -al \/usr\/local\/bin\/\r\n<\/pre>\n

ccat Command Executable Files<\/p>\n
If for some reasons the\u00a0ccat<\/strong>\u00a0file from your executable system path has no executable bit set, issue the below command to set executable permissions for all system users.<\/p>\n
# chmod +x \/usr\/local\/bin\/ccat\r\n<\/pre>\n
In order to test\u00a0ccat<\/strong>\u00a0utility capabilities against a system configuration file, issue the below commands. The content of the displayed files should be highlighted according to file programming language sytnax, as illustrated in the below command examples.<\/p>\n
# ccat \/etc\/sysconfig\/network-scripts\/ifcfg-ens33 \r\n# ccat \/etc\/fstab \r\n<\/pre>\n

ccat Command Usage<\/p>\n<\/div>\n
In order to replace\u00a0cat command<\/a>\u00a0with\u00a0ccat command<\/strong>\u00a0system wide, add a bash alias for\u00a0ccat<\/strong>\u00a0in system\u00a0bashrc<\/strong>file, log out from the system and log in back again to apply the configuration.<\/p>\n
-------------- On CentOS, RHEL & Fedora --------------<\/strong> \r\n# echo \"alias cat='\/usr\/local\/bin\/ccat'\" >> \/etc\/bashrc \r\n# exit\r\n\r\n-------------- On Debiab & Ubuntu --------------<\/strong> \r\n# echo \"alias cat='\/usr\/local\/bin\/ccat'\" >> \/etc\/profile\r\n# exit\r\n<\/pre>\n
Finally, run\u00a0cat command<\/strong>\u00a0against an arbitrary configuration file to test if\u00a0ccat<\/strong>\u00a0alias has replaced\u00a0cat command<\/strong>, as shown in the below example. The output file syntax should be highlighted now.<\/p>\n
# cat .bashrc\r\n<\/pre>\n
\n
\"Replace<\/a><\/p>\n
Replace cat Command with ccat<\/p>\n<\/div>\n
ccat<\/strong>\u00a0utility can also be used to concatenate multiple files and display the output in HTML format, as illustrated in the below example.<\/p>\n
# ccat --html \/etc\/fstab \/etc\/sysconfig\/network-scripts\/ifcfg-ens33> \/var\/www\/html\/ccat.html\r\n<\/pre>\n
However, you will need a web server installed in your system, such as Apache HTTP server or Nginx, to display the content of the HTML file, as illustrated in the below screenshot.<\/p>\n
