 ===== Bash =====
   * Use Bash auto-completion (''source /etc/bash_completion''). Some tools have plugins, e.g. many [[https://metacpan.org/pod/Bash::Completion|Perl tools]].
   * ''export HISTCONTROL=ignoreboth'' results in bash history ignoring duplicate entries and entries starting with a space.
-  * See ''/ha/home/bojar/diplomka/granty/cracker-2015/mtm-2016-organization/accounts-mtm16/bash-profile-for-ufal-accounts'' for:
-    * bash history local in the current directory
+==== Directory-local Bash history ====
+  * Ondřej Bojar prefers to store the history in each directory in ''.history-bojar''. See ''/home/bojar/diplomka/granty/cracker-2015/mtm-2016-organization/accounts-mtm16/bash-profile-for-ufal-accounts''
+    * Note that this creates the ".history-your-name" wherever you have write access and some ÚFALers are not happy with this. In addition everyone sees what you did (this may be useful, but be careful).
+  * Ondřej Dušek (''/home/odusek/.bashrc'') uses a variant more friendly to others, which saves the histories in his home (but does not handle renamed directories):<code>
+if [ -z "$USER" ]; then
+    export USER=`whoami`
+fi
+# Store all history with times and directories
+function store_history () {
+    history 1 | awk '($2 !~ "^[mr]?cd[0-9a-z]?$") {$1="_T="strftime("%Y%m%d_%H:%M:%S_") PROCINFO["ppid"] "_PWD="  ENVIRON["PWD"] "\t"; $2=gensub("^_T=[-_0-9:]*[ \t]* *", "", 1, $2); $2=gensub("^_P=[^ \t]* *", "", 1, $2); print;}' >> ~/.history-all-$USER
+}
+export PROMPT_COMMAND="store_history"
+# Grep history
+function dhist (){
+    DIR=`pwd`
+    command grep "_PWD=$DIR"$'\t'".*$@" ~/.history-all-$USER | tail -n 30
+}
+function hist (){
+    if [ "$#" -eq 0 ]; then
+        tail -n 30 ~/.history-all-$USER
+    else
+        command grep "$@" ~/.history-all-$USER | tail -n 30
+    fi
+}
+</code>
+==== Colorful manpages ====
+Add this to your .bashrc (tested on .zshrc). Colors can be easily customized.
+<code>
+man () {
+        env LESS_TERMCAP_mb=$'\E[01;31m' \
+        LESS_TERMCAP_md=$'\E[01;38;5;74m' \
