<p>New page: SORT(1) UNIX Programmer&#039;s Manual SORT(1) == NAME == sort - sort or merge files == SYNOPSIS == sort [ -mubdfinrt_________x ] [ +_p_o_s_1 [ -_p_o_s_2 ...</p> <p><b>New page</b></p><div>SORT(1) UNIX Programmer's Manual SORT(1)<br /> <br /> <br /> <br /> == NAME ==<br /> sort - sort or merge files<br /> <br /> == SYNOPSIS ==<br /> sort [ -mubdfinrt_________x ] [ +_p_o_s_1 [ -_p_o_s_2 ] ] ... [ -o name ] [<br /> -T directory ] [ name ] ...<br /> <br /> == DESCRIPTION ==<br /> _S_o_r_t sorts lines of all the named files together and writes<br /> the result on the standard output. The name `-' means the<br /> standard input. If no input files are named, the standard<br /> input is sorted.<br /> <br /> The default sort key is an entire line. Default ordering is<br /> lexicographic by bytes in machine collating sequence. The<br /> ordering is affected globally by the following options, one<br /> or more of which may appear.<br /> <br /> b Ignore leading blanks (spaces and tabs) in field com-<br /> parisons.<br /> <br /> d `Dictionary' order: only letters, digits and blanks are<br /> significant in comparisons.<br /> <br /> f Fold upper case letters onto lower case.<br /> <br /> i Ignore characters outside the ASCII range 040-0176 in<br /> nonnumeric comparisons.<br /> <br /> n An initial numeric string, consisting of optional<br /> blanks, optional minus sign, and zero or more digits<br /> with optional decimal point, is sorted by arithmetic<br /> value. Option n implies option b.<br /> <br /> r Reverse the sense of comparisons.<br /> <br /> t_x `Tab character' separating fields is _x.<br /> <br /> The notation +_p_o_s_1 -_p_o_s_2 restricts a sort key to a field<br /> beginning at _p_o_s_1 and ending just before _p_o_s_2. _P_o_s_1 and<br /> _p_o_s_2 each have the form _m._n, optionally followed by one or<br /> more of the flags bdfinr, where _m tells a number of fields<br /> to skip from the beginning of the line and _n tells a number<br /> of characters to skip further. If any flags are present<br /> they override all the global ordering options for this key.<br /> If the b option is in effect _n is counted from the first<br /> nonblank in the field; b is attached independently to _p_o_s_2.<br /> A missing ._n means .0; a missing -_p_o_s_2 means the end of the<br /> line. Under the -t_x option, fields are strings separated by<br /> _x; otherwise fields are nonempty nonblank strings separated<br /> by blanks.<br /> <br /> When there are multiple sort keys, later keys are compared<br /> only after all earlier keys compare equal. Lines that oth-<br /> erwise compare equal are ordered with all bytes significant.<br /> <br /> These option arguments are also understood:<br /> <br /> c Check that the input file is sorted according to the<br /> ordering rules; give no output unless the file is out<br /> of sort.<br /> <br /> m Merge only, the input files are already sorted.<br /> <br /> o The next argument is the name of an output file to use<br /> instead of the standard output. This file may be the<br /> same as one of the inputs.<br /> <br /> T The next argument is the name of a directory in which<br /> temporary files should be made.<br /> <br /> u Suppress all but one in each set of equal lines.<br /> Ignored bytes and bytes outside keys do not participate<br /> in this comparison.<br /> <br /> Examples. Print in alphabetical order all the unique spel-<br /> lings in a list of words. Capitalized words differ from<br /> uncapitalized.<br /> <br /> sort -u +0f +0 list<br /> <br /> Print the password file (_p_a_s_s_w_d(5)) sorted by user id number<br /> (the 3rd colon-separated field).<br /> <br /> sort -t: +2n /etc/passwd<br /> <br /> Print the first instance of each month in an already sorted<br /> file of (month day) entries. The options -um with just one<br /> input file make the choice of a unique representative from a<br /> set of equal lines predictable.<br /> <br /> sort -um +0 -1 dates<br /> <br /> == FILES ==<br /> /usr/tmp/stm*, /tmp/* first and second tries for tem-<br /> porary files<br /> <br /> == SEE ALSO ==<br /> [[32v 1m uniq|uniq(1)]], [[32v 1m comm|comm(1)]], [[32v 1m rev|rev(1)]], [[32v 1m join|join(1)]]<br /> <br /> == DIAGNOSTICS ==<br /> Comments and exits with nonzero status for various trouble<br /> conditions and for disorder discovered under option -c.<br /> <br /> == BUGS ==<br /> Very long lines are silently truncated.<br /> <br /> [[Category:32v man section 1]]</div>
