<\/u><\/h5>\n<pre>\nThe  history command performs  one of  several operations\nrelated  to  recently-executed  commands  recorded  in  a\nhistory list. Each of these recorded commands is referred\nto  as an  ``event''.  When specifying  an  event to  the\nhistory command, the following forms may be used:\n\n[1] A  number: if positive,  it refers to the  event with\nthat number  (all events are numbered starting  at 1). If\nthe number  is negative, it selects an  event relative to\nthe current event (-1 refers to the previous event, -2 to\nthe one  before that, and so  on). Event 0  refers to the\ncurrent  event.\n\n\n[2] A string: selects  the most recent event that matches\nthe string.  An event is  considered to match  the string\neither if the string is  the same as the first characters\nof the event,  or if the string matches  the event in the\nsense of the string match command.\n\n<\/pre>\n","protected":false},"excerpt":{"rendered":"<p>A UNIX Command $history 11 ls 12 vi kernel_start.s 13 as kernel_start.s 14 ls -l 15 sh a.out 16 ls 17 vi kernel_start.s 18 ls 19 cd linux\/ 20 ls 21 cd boot\/ 22 ls 23 as boot.s 24 cd 25 cd linux-2.6 26 ls 27 cd arch\/ 28 ls 29 cd .. 30 find &hellip; <\/p>\n<p class=\"link-more\"><a href=\"https:\/\/www.trueangle.org\/index.php\/2011\/08\/11\/history-shows-command-history\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;history &#8211; shows command history&#8221;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/posts\/5400"}],"collection":[{"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/comments?post=5400"}],"version-history":[{"count":0,"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/posts\/5400\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/media?parent=5400"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/categories?post=5400"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.trueangle.org\/index.php\/wp-json\/wp\/v2\/tags?post=5400"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
