Sample eshell session: --------------------- ~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | xa= rgs -n1 -t | wc -l 92 ~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | xa= rgs -n1 -t | wc -l 32 ~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | wc= -l 54 ~/Documents/battle-field [ ] # find -L islands-page/ -name '*.bemhtml' | wc= -l 54 No other process is writing to the root folder or its subdirectiories. Correct number of lines is 54. Works fine in *shell*, *ansi-term*, spawned as async command or in any externall shell. Unrelated to this issue, there's another potential bug. Adding NUL as separator throws Emacs into infinite 'visual bell' - totally unresponsive - can only be nuked: -------------------------------- find -L islands-page/ -name '*.bemhtml' -print0 | xargs -0 -n1 echo In GNU Emacs 24.3.1 (x86_64-apple-darwin13.2.0, NS apple-appkit-1265.20) of 2014-06-08 on 5.255.234.126-red.dhcp.yndx.net Windowing system distributor `Apple', version 10.3.1265 Configured using: `configure '--prefix=3D/usr/local/Cellar/emacs/24.3' '--without-dbus' '--enable-locallisppath=3D/usr/local/share/emacs/site-lisp' '--infodir=3D/usr/local/Cellar/emacs/24.3/share/info/emacs' '--without-gnutls' '--with-ns' '--disable-ns-self-contained' 'CC=3Dclang'' Important settings: value of $LC_CTYPE: UTF-8 locale-coding-system: utf-8-unix default enable-multibyte-characters: t Major mode: EShell Minor modes in effect: magit-auto-revert-mode: t yas-global-mode: t yas-minor-mode: t global-flycheck-mode: t which-function-mode: t global-company-mode: t company-mode: t helm-mode: t helm-descbinds-mode: t helm-match-plugin-mode: t helm-occur-match-plugin-mode: t erc-truncate-mode: t erc-track-mode: t erc-spelling-mode: t global-diff-hl-mode: t diff-auto-refine-mode: t winner-mode: t global-undo-tree-mode: t undo-tree-mode: t global-anzu-mode: t anzu-mode: t projectile-global-mode: t projectile-mode: t shell-dirtrack-mode: t volatile-highlights-mode: t global-hl-line-mode: t recentf-mode: t savehist-mode: t show-smartparens-global-mode: t global-auto-revert-mode: t delete-selection-mode: t prelude-global-mode: t prelude-mode: t tooltip-mode: t mouse-wheel-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t size-indication-mode: t column-number-mode: t line-number-mode: t transient-mark-mode: t Recent input: C-n C-p C-n w w C-p C-n w w C-t r e a d C-n C-n C-p w w M-h M-` C-g M-; C-t C-s w w C-- C-- w w C-- C-- C-- C-p C-n w w w w =D0=B1 =D0=B1 C-=D1=85 w w w w C-/ C-t C-s w w C-p C-n w w C-p C-n C-t C-s C-p C-p C-p C-p C-p C-p C-n C-n C-n C-n C-n C-n C-n C-d C-d C-d C-t C-s C-c C-b b b C-n C-n C-n C-n C-n C-n C-p C-n w w C-n C-d C-d C-t C-s C-d C-t C-s C-c C-b b b C-n C-n C-n C-n C-n C-n C-n C-n C-p C-n w w C-n C-d C-d C-t C-s C-c C-b w w b b C-c s w w b b C-d M-h M-` C-g M-; C-t C-s w w b b b j s M-< C-v C-v C-v C-v C-v C-v M-< b b C-n C-n C-p C-n C-p C-n C-p C-n C-n C-n C-p C-n C-n C-t m p w d c d SPC o d b a d o c C-c C-l C-g C-t C-f d o c u b a t C-z p a t h e s h e l M-e C-c C-l f i n d C-n C-p C-n C-n C-n C-p C-n M-p M-p C-b C-b C-b C-b C-b C-b C-b C-e M-p C-t r e p a r o r t SPC e m a Recent messages: Mark set Saving file /Users/kozin/Documents/Speak/pYatnitsa/Expr.js...
