 You can search in many programs by using `/`.
-Most programs let you clearn the highlighting with `<Esc>+u`.

-## Automatic Renaming
-
-There are a bunch of files:
-
-* Column CV.aux
-* Column CV.log
-* Column CV.out
-* Column CV.pdf
-* Column CV.tex
-* tccv.cls
-
-Goal: swap the word "Column" for "Alice" in all files.
-
-```sh
-IFS=$'\n'
-for f in $(find . -name "Col*"); do
-mv "$f" $(echo "$f" | sed s/Column/Alice/)
-done
-```
-
-IFS is the field separator.  This is required to denote the different files as marked by a new line, and not the spaces.
-
-(Alternatively, just install `renameutils` and do `rename Column Alice *`)
-
-## Arguments and Input
-
-The `rm' program takes arguments, but not `stdin' from a keyboard, and therefore programs cannot pipe results into rm.
-To fix this, use `xargs` to turn the stdin into an argument.
-For example, if we have a list of files called `list.txt' then we could use cat as so:
-
-```sh
-cat list.txt | xargs rm
-```
-
-Of course if spaces are included in the file, you would have to account for that.
-
-## Numbers
-
-Add number to variables with:
-
-* `let "var=var+1"`
-* `let "var+=1"`
-* `let "var++"`
-* `((++var))`
-* `((var=var+1))`
-* `((var+=1))`
-* `var=$(expr $var + 1)`
-
-`((n--))` works identically.
-
-### POSIX WARNING
-
-The number commands above work in `bash`, but not in bare-ass POSIX shells, such as `dash`.
-
-Instead, you might do:
-
-```sh
-x=2
-x=$(( x +1 ))
-x=$(( x*x ))
-```
-
-## Finding Duplicate Files
-
-```sh
-find . -type f -exec md5sum '{}' ';' | sort | uniq --all-repeated=separate -w 15 > all-files.txt
-```
-
-## Output random characters
-
-```sh
-cat /dev/urandom | tr -cd [:alnum:] | dd bs=1 count=200 status=none && echo
-```
-
-## Temporary Working Directory
-
-Try something out in a random directory in `/tmp` so the files will be deleted when you next shut down.
-
-```sh
-mktemp -d
-```
-
-That gives you a random directory to mess about in.
-
-```sh
-   dir=$(mktemp -d)
-   for x in {A..Z}; do
-      fortune > "$dir"/chimpan-$x
-   done
-   cd $dir
-```
-
-### POSIX WARNING
-
-These smart-brackets are a bash feature.
-If you try to use `{A..Z}` in dash, it will think of this as a single item.
