Windows console applications. File managers

Operating systems : Windows

FAR Manager : DOS Navigator : File Commander

The concept and requirements to file manager had formed itself back in the DOS epoch. With the spread of operating systems with graphical user interface, other applications facilitating files handling emerged. But for many tasks and for many users orthodox file managers remain the most convenient option.

There are file managers with graphical user interface here for a long time already, however console file managers still hold on not only their proper niche, but as well a part of the space belonging in theory to file managers with a GUI. Nowadays file managers can, all in all, the same and in general the same way, but text-based file managers are more responsive to user actions. Also, even if it is not topical enough now, console file managers require less system resources, than GUI file managers of comparable functionality.

Unzip multiple files. Linux

 

Unzip multiple zip files into one directory by Linux command line unzip. Contrary to possible expectations, "unzip *.zip" is not going to work, *.zip should be put into quotes: unzip "*.zip" There may be files with the same names in these archives. To avoid overwriting: unzip -B "*.zip" "Unzip -B" makes unzip to overwrite duplicates during extraction process, but saving a backup copy of each overwritten file. The names for these backup copy files are created by adding tilde ("~") at the end of the original names of the files. If a file extension is present, then "~" is added after it. If that is not enough, unique sequence number (up to 5 digits) is appended after the "~". "Unzip -B" is not too practical. For example, since when the sequence number range for numbered backup files gets exhausted (99999, or 65535 for 16-bit systems), the backup file with the maximum sequence number is deleted and replaced by the new backup version without notice ( More on the subject ). The number of files in an archive may not be always known in advance or may be more than possible sequence number range, so "Unzip -B" is not a great choice. Renaming duplicate files by adding "~" at the end of their names, after the extension, is not too convenient either. But another built-in option is even worse. If the "-B" modifier is not used, each time a file with same name as there already unpacked is being extracted, unzip asks "replace example.txt? [y]es, [n]o, [A]ll, [N]one, [r]ename:". And each time "r" must be hit, then a new name has to be input. So some bash or another script solving the problem should probably be prepared and used instead.

Lynx browser. Creating sitemap.xml

 

There are more than few online services for sitemap.xml generation. But it is also possible to do it yourself, by means of lynx web browser and several Linux command line utilities. An example bash script employing them, named "sitemap.sh" is described below. Bash script creating a sitemap.xml file: #!/bin/bash cd /home/me/sitemap/www/ lynx -crawl -traversal -accept_all_cookies -connect_timeout=30 http://www.compmiscellanea.com/ > /dev/null cd /home/me/sitemap/www2/ lynx -crawl -traversal -accept_all_cookies -connect_timeout=30 http://compmiscellanea.com/ > /dev/null cat /home/me/sitemap/www2/traverse.dat >> /home/me/sitemap/www/traverse.dat cat /home/me/sitemap/www/traverse.dat | sed -e 's/\<www\>\.//g' | sort | uniq > /home/me/sitemap/sitemap/sitemap.xml sed -i 's/\&/\&amp\;/g' /home/me/sitemap/sitemap/sitemap.xml sed -i "s/'/\&apos\;/g" /home/me/sitemap/sitemap/sitemap.xml sed -i 's/"/\&quot\;/g' /home/me/sitemap/sitemap/sitemap.xml sed -i 's/>/\&gt\;/g' /home/me/sitemap/sitemap/sitemap.xml sed -i 's/</\&lt\;/g' /home/me/sitemap/sitemap/sitemap.xml sed -i 's/http:\/\//http:\/\/www\./g' /home/me/sitemap/sitemap/sitemap.xml sed -i -e 's/^/<url><loc>/' /home/me/sitemap/sitemap/sitemap.xml sed -i -e 's/$/<\/loc><\/url>/' /home/me/sitemap/sitemap/sitemap.xml sed -i -e '1 i <?xml version="1\.0" encoding="UTF-8"?>\r\r<urlset xmlns="http:\/\/www\.sitemaps\.org\/schemas\/sitemap\/0\.9" xmlns:xsi="http:\/\/www\.w3\.org\/2001\/XMLSchema-instance" xsi:schemaLocation="http:\/\/www\.sitemaps\.org\/schemas\/sitemap\/0\.9 http:\/\/www\.sitemaps\.org\/schemas\/sitemap\/0\.9\/sitemap\.xsd">\r\r<!-- created by sitemap.sh from http:\/\/www.compmiscellanea.com\/en\/lynx-browser-creating-sitemap.xml\.htm -->\r\r' /home/me/sitemap/sitemap/sitemap.xml sed -i -e '$ a \\r</urlset>' /home/me/sitemap/sitemap/sitemap.xml sed -i '/static/d' /home/me/sitemap/sitemap/sitemap.xml echo "...Done" After the bash script file is prepared: "chmod +x sitemap.sh" to make it executable. Download sitemap.sh in sitemap.sh.tar.gz archive ( After downloading and unpacking it, put a web site name with "www" instead of http://www.compmiscellanea.com/ and a web site name without "www" instead of http://compmiscellanea.com/ in the file. Replace "static" in the last line of the file by a string unnecessary links should possess to be removed. Then "chmod +x sitemap.sh". Then run sitemap.sh ). Commentary Download sitemap2.sh with line by line commentary in sitemap2.sh.tar.gz archive. Before running the bash script, three folders should be created. Since lynx browser may miss some links if a web site domain name to be crawled is put with or without "www", bash script runs lynx twice, crawling the web site by its name with "www" and crawling the web site by its name without "www". The two result files are put into two of these separate folders, here they are "/home/me/sitemap/www/" and "/home/me/sitemap/www2/". And "/home/me/sitemap/sitemap/" is for sitemap.xml created in the end. 1. Path to bash: #!/bin/bash 2. Going to a folder - lynx browser is going to put there the files obtained from crawling a web site with "www" in its name: cd /home/me/sitemap/www/ 3. Running lynx browser to crawl a web site.
