  9. .SH DESCRIPTION
  10. .PP
  11. \f[C]exa\f[] is a modern replacement for \f[C]ls\f[].
  12. It uses colours for information by default, helping you distinguish
  13. between many types of files, such as whether you are the owner, or in
  14. the owning group.
  15. It also has extra features not present in the original \f[C]ls\f[], such
  16. as viewing the Git status for a directory, or recursing into directories
  17. with a tree view.

  179. .SH EXAMPLES
  180. .PP
  181. To display a list of files, with the largest at the top:
  182. .IP
  183. .nf
  184. \f[C]
  185. exa\ \-\-reverse\ \-\-sort=size
  186. \f[]
  187. .fi
  188. .PP
  189. To display a tree of files, three levels deep:
  190. .IP
  191. .nf
  192. \f[C]
  193. exa\ \-\-long\ \-\-tree\ \-\-level=3
  194. \f[]
  195. .fi
  196. .SH ENVIRONMENT VARIABLES
  197. .PP
  198. exa responds to the following environment variables:
  199. .SS \f[C]COLUMNS\f[]
  200. .PP
  201. Overrides the width of the terminal, in characters.
  202. For example, \f[C]COLUMNS=80\ exa\f[] will show a grid view with a
  203. maximum width of 80 characters.
  204. .PP
  205. This option won\[aq]t do anything when exa\[aq]s output doesn\[aq]t
  206. wrap, such as when using the \f[C]\-\-long\f[] view.
  207. .SS \f[C]EXA_STRICT\f[]
  208. .PP
  209. Enables \f[I]strict mode\f[], which will make exa error when two
  210. command\-line options are incompatible.
  211. Usually, options can override each other going right\-to\-left on the
  212. command line, so that exa can be given aliases: creating an alias
  213. \f[C]exa=exa\ \-\-sort=ext\f[] then running \f[C]exa\ \-\-sort=size\f[]
  214. with that alias will run \f[C]exa\ \-\-sort=ext\ \-\-sort=size\f[], and
  215. the sorting specified by the user will override the sorting specified by
  216. the alias.
  217. In strict mode, the two options will not co\-operate, and exa will
  218. error.
  219. .PP
  220. This option is intended for use with automated scripts and other
  221. situations where you want to be \f[I]certain\f[] you\[aq]re typing in
  222. the right command.
  223. .SS \f[C]EXA_GRID_ROWS\f[]
  224. .PP
  225. Limits the grid\-details view (\f[C]exa\ \-\-grid\ \-\-long\f[]) so
  226. it\[aq]s only activated when at least the given number of rows of output
  227. would be generated.
  228. With widescreen displays, it\[aq]s possible for the grid to look very
  229. wide and sparse, on just one or two lines with none of the columns
  230. lining up.
  231. By specifying a minimum number of rows, you can only use the view if
  232. it\[aq]s going to be worth using.
  233. .SS \f[C]LS_COLORS\f[] and \f[C]EXA_COLORS\f[]
  234. .PP
  235. The \f[C]EXA_COLORS\f[] variable is the traditional way of customising
  236. the colours used by \f[C]ls\f[].
  237. .PP
  238. You can use the \f[C]dircolors\f[] program to generate a script that
  239. sets the variable from an input file, or if you don\[aq]t mind editing
  240. long strings of text, you can just type it out directly.
  241. These variables have the following structure:
  242. .IP \[bu] 2
  243. A list of key\-value pairs separated by \f[C]=\f[], such as
  244. \f[C]*.txt=32\f[].
  245. .IP \[bu] 2
  246. Multiple ANSI formatting codes are separated by \f[C];\f[], such as
  247. \f[C]*.txt=32;1;4\f[].
  248. .IP \[bu] 2
  249. Finally, multiple pairs are separated by \f[C]:\f[], such as
  250. \f[C]*.txt=32:*.mp3=1;35\f[].
  251. .PP
  252. The key half of the pair can either be a two\-letter code or a file
  253. glob, and anything that\[aq]s not a valid code will be treated as a
  254. glob, including keys that happen to be two letters long.
  255. .PP
  256. \f[C]LS_COLORS\f[] can use these ten codes:
  257. .IP \[bu] 2
  258. \f[B]di\f[], directories
  259. .IP \[bu] 2
  260. \f[B]ex\f[], executable files
  261. .IP \[bu] 2
  262. \f[B]fi\f[], regular files
  263. .IP \[bu] 2
  264. \f[B]pi\f[], named pipes
  265. .IP \[bu] 2
  266. \f[B]so\f[], sockets
  267. .IP \[bu] 2
  268. \f[B]bd\f[], block devices
  269. .IP \[bu] 2
  270. \f[B]cd\f[], character devices
  271. .IP \[bu] 2
  272. \f[B]ln\f[], symlinks
  273. .IP \[bu] 2
  274. \f[B]or\f[], symlinks with no target
  275. .PP
  276. \f[C]EXA_COLORS\f[] can use many more:
  277. .IP \[bu] 2
  278. \f[B]ur\f[], the user\-read permission bit
  279. .IP \[bu] 2
  280. \f[B]uw\f[], the user\-write permission bit
  281. .IP \[bu] 2
  282. \f[B]ux\f[], the user\-execute permission bit for regular files
  283. .IP \[bu] 2
  284. \f[B]ue\f[], the user\-execute for other file kinds
  285. .IP \[bu] 2
  286. \f[B]gr\f[], the group\-read permission bit
  287. .IP \[bu] 2
  288. \f[B]gw\f[], the group\-write permission bit
  289. .IP \[bu] 2
  290. \f[B]gx\f[], the group\-execute permission bit
  291. .IP \[bu] 2
  292. \f[B]tr\f[], the others\-read permission bit
  293. .IP \[bu] 2
  294. \f[B]tw\f[], the others\-write permission bit
  295. .IP \[bu] 2
  296. \f[B]tx\f[], the others\-execute permission bit
  297. .IP \[bu] 2
  298. \f[B]su\f[], setuid, setgid, and sticky permission bits for files
  299. .IP \[bu] 2
  300. \f[B]sf\f[], setuid, setgid, and sticky for other file kinds
  301. .IP \[bu] 2
  302. \f[B]xa\f[], the extended attribute indicator
  303. .IP \[bu] 2
  304. \f[B]sn\f[], the numbers of a file\[aq]s size
  305. .IP \[bu] 2
  306. \f[B]sb\f[], the units of a file\[aq]s size
  307. .IP \[bu] 2
  308. \f[B]df\f[], a device\[aq]s major ID
  309. .IP \[bu] 2
  310. \f[B]ds\f[], a device\[aq]s minor ID
  311. .IP \[bu] 2
  312. \f[B]uu\f[], a user that\[aq]s you
  313. .IP \[bu] 2
  314. \f[B]un\f[], a user that\[aq]s someone else
  315. .IP \[bu] 2
  316. \f[B]gu\f[], a group that you belong to
  317. .IP \[bu] 2
  318. \f[B]gn\f[], a group you aren\[aq]t a member of
  319. .IP \[bu] 2
  320. \f[B]lc\f[], a number of hard links
  321. .IP \[bu] 2
  322. \f[B]lm\f[], a number of hard links for a regular file with at least two
  323. .IP \[bu] 2
  324. \f[B]ga\f[], a new flag in Git
  325. .IP \[bu] 2
  326. \f[B]gm\f[], a modified flag in Git
  327. .IP \[bu] 2
  328. \f[B]gd\f[], a deleted flag in Git
  329. .IP \[bu] 2
  330. \f[B]gv\f[], a renamed flag in Git
  331. .IP \[bu] 2
  332. \f[B]gt\f[], a modified metadata flag in Git
  333. .IP \[bu] 2
  334. \f[B]xx\f[], "punctuation", including many background UI elements
  335. .IP \[bu] 2
  336. \f[B]da\f[], a file\[aq]s date
  337. .IP \[bu] 2
  338. \f[B]in\f[], a file\[aq]s inode number
  339. .IP \[bu] 2
  340. \f[B]bl\f[], a file\[aq]s number of blocks
  341. .IP \[bu] 2
  342. \f[B]hd\f[], the header row of a table
  343. .IP \[bu] 2
  344. \f[B]lp\f[], the path of a symlink
  345. .IP \[bu] 2
  346. \f[B]cc\f[], an escaped character in a filename
  347. .IP \[bu] 2
  348. \f[B]bO\f[], the overlay style for broken symlink paths
  349. .PP
  350. Values in \f[C]EXA_COLORS\f[] override those given in
  351. \f[C]LS_COLORS\f[], so you don\[aq]t need to re\-write an existing
  352. \f[C]LS_COLORS\f[] variable with proprietary extensions.
  353. .PP
  354. Unlike some versions of \f[C]ls\f[], the given ANSI values must be valid
  355. colour codes: exa won\[aq]t just print out whichever characters are
  356. given.
  357. The codes accepted by exa are:
  358. .IP \[bu] 2
  359. \f[C]1\f[], for bold
  360. .IP \[bu] 2
  361. \f[C]4\f[], for underline
  362. .IP \[bu] 2
  363. \f[C]31\f[], for red text
  364. .IP \[bu] 2
  365. \f[C]32\f[], for green text
  366. .IP \[bu] 2
  367. \f[C]33\f[], for yellow text
  368. .IP \[bu] 2
  369. \f[C]34\f[], for blue text
  370. .IP \[bu] 2
  371. \f[C]35\f[], for purple text
  372. .IP \[bu] 2
  373. \f[C]36\f[], for cyan text
  374. .IP \[bu] 2
  375. \f[C]37\f[], for white text
  376. .IP \[bu] 2
  377. \f[C]38;5;\f[]\f[I]\f[C]nnn\f[]\f[], for a colour from 0 to 255 (replace
  378. the \f[I]nnn\f[] part)
  379. .PP
  380. Many terminals will treat bolded text as a different colour, or at least
  381. provide the option to.
  382. .PP
  383. exa provides its own built\-in set of file extension mappings that cover
  384. a large range of common file extensions, including documents, archives,
  385. media, and temporary files.
  386. Any mappings in the environment variables will override this default
  387. set: running exa with \f[C]LS_COLORS="*.zip=32"\f[] will turn zip files
  388. green but leave the colours of other compressed files alone.
  389. .PP
  390. You can also disable this built\-in set entirely by including a
  391. \f[C]reset\f[] entry at the beginning of \f[C]EXA_COLORS\f[].
  392. So setting \f[C]EXA_COLORS="reset:*.txt=31"\f[] will highlight only text
  393. files; setting \f[C]EXA_COLORS="reset"\f[] will highlight nothing.
  394. .SS Examples
  395. .IP \[bu] 2
  396. Disable the "current user" highlighting: \f[C]EXA_COLORS="uu=0:gu=0"\f[]
  397. .IP \[bu] 2
  398. Turn the date column green: \f[C]EXA_COLORS="da=32"\f[]
  399. .IP \[bu] 2
  400. Highlight Vagrantfiles: \f[C]EXA_COLORS="Vagrantfile=1;4;33"\f[]
  401. .IP \[bu] 2
  402. Override the existing zip colour: \f[C]EXA_COLORS="*.zip=38;5;125"\f[]
  403. .IP \[bu] 2
  404. Markdown files a shade of green, log files a shade of grey:
  405. \f[C]EXA_COLORS="*.md=38;5;121:*.log=38;5;248"\f[]
  406. .SS BUILT\-IN EXTENSIONS
  407. .IP \[bu] 2
