In Unix’s bash shell, for instance, there are some nice features for command line completion. If you type the word history<\/TT> you’ll get a list of the last commands you executed, preceeded by numbers. If you type !<\/TT> immediately followed by that number, it will re-run that command. If you type !<\/TT> prefixing the start of some command, it will hunt back through the history and run the first command started with said prefix.<\/p>\n
Today while working the XP DOS Box, I bumped a function key and got a pop-up box of my command history. In all my years working with NT, 2000, and XP, I’d never seen that before. So, wanting to recreate it, I researched what it was and how to do it.<\/p>\n
The program to thank is DOSKEY. Pressing F7 while at a command problem brings up the command history menu that surprised me. If you already know a command’s number, because you saw it in the list, F9 will let you just enter the number directly. If you type a letter and press F8, it will cycle through all commands starting with that letter.<\/p>\n
Pressing ALT-F7 will clear the command history, which on Unix is the same as typing history -c<\/TT>.<\/p>\n
Unix has a lot more options when it comes to the history<\/TT> and fc<\/TT> (fix command) than Windows, but it was nice to see a small subset implemented. <\/p>\n
Just another small trick to add to the productivity bag.<\/p>\n","protected":false},"excerpt":{"rendered":"
Hey, did you know F7 brings up a command history in CMD.EXE? It’s done that for years, and this was the first I’d ever run into it.<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[67,106],"tags":[],"class_list":["post-212","post","type-post","status-publish","format-standard","hentry","category-how-to","category-windows"],"_links":{"self":[{"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/posts\/212","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/comments?post=212"}],"version-history":[{"count":0,"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/posts\/212\/revisions"}],"wp:attachment":[{"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/media?parent=212"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/categories?post=212"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wls.wwco.com\/blog\/wp-json\/wp\/v2\/tags?post=212"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
