How do I convert a document from tex/latex to pdf
To convert TeX/LaTeX directly to PDF

    pdflatex file.tex  (produces file.pdf)

Available on the Pentiums ie linux but not Alphas.
Alternatively or if the file has pictures/figures in it, the below will work so long as the figures are of type eps (encapsulated postscript) since those are the only kind that dvips will really cope with. However .gif/.jpg files can usually be converted to .eps fairly easily with xv or gimp.

If you have a latex document called fred.tex then a recipe which works
would be:

# Run latex on it
  latex fred.tex
# 2nd, 3rd time if there are forward references which need to be right
  latex fred.tex
  latex fred.tex

# Convert to postscript -t specifies the paper type (not needed
# normally, but otherwise the ps2pdf will guess letter size), -Peel
# sets things up for a typical printer, -o says where the output will
# go (a file in this case).

  dvips -t a4 -R -Peel -o fred.ps fred.dvi

# Convert postscript to pdf
  ps2pdf fred.ps fred.pdf

This should result in a .pdf file fred.pdf

How do I convert a .dvi file to a .ps file
```
dvips -o filename.ps filename.dvi
```
This will produce filename.ps from filename.dvi. The .dvi part is optional. ie
```
dvips -o filename2.ps filename
```
will work just as well.
How do I convert a .ps file to a ascii text
Use the command ps2ascii which will give you a text-only version of the dvi file ie ps2ascii file.ps will output the ascii text on the screen, while ps2ascii file.ps file will save the output to a file called file.
Use ps2ascii --help for more options.
How do I convert a .ps file to other vector formats eg graphical for further processing
Use the command pstoedit. Example usage to convert a .ps file called house.ps to a .fig file is
```
	pstoedit -f fig house.ps house.fig
```
The pstoedit website contains a complete list of supported formats.
How do I convert my .dvi file to text
First use dvips to convert the file to postscript, then use ps2ascii to convert the postscript to ascii text. You will lose the pictures and other graphics, but maintain the text of the document. This is sometimes useful if you accidently delete the .tex file. ie to get the ascii from myfile.dvi into a file called myfile
```
dvips -o myfile.ps myfile.dvi
ps2ascii myfile.ps myfile
```
How do I convert a document from .dvi format to .pdf
Use dvipdf.

But sometimes this produces a file in which the superscripts do not look right in acroread. Often when you magnify the file in acroread eg to 3005, the superscripts look correct, as they do when using xpdf to view the resultant .pdf file.
A way to overcome this problem is to convert the .tex code directly to pdf with pdflatex or pdftex.
dos to unix (or how to remove the ^M characters in a file)
d2u is a very simple script which converts from DOS or Mac text formats to unix (the name is historical).
usage is
```
  d2u file
```
it renames that to file.old and creates a new one with the converted contents.
It also removes Ctrl-Z which occurs at the end of some DOS files.
mtools has a -t option to do a text transfer.
