Here's the list of some UNIX commands that can be emulated
using SED. Please, if know about others, contribute!


 UNIX | SED
 -------------+----------------------------------------------------------------
 cat | sed ':'
 cat -s | sed '1s/^$//p;/./,/^$/!d'
 tac | sed '1!G;h;$!d'
 grep | sed '/patt/!d'
 grep -v | sed '/patt/d'
 head | sed '10q'
 head -1 | sed 'q'
 tail | sed -e ':a' -e '$q;N;11,$D;ba'
 tail -1 | sed '$!d'
 tail -f | sed -u '/./!d'
 cut -c 10 | sed 's/\(.\)\{10\}.*/\1/'
 cut -d: -f4 | sed 's/\(\([^:]*\):\)\{4\}.*/\2/'
 tr A-Z a-z | sed 'y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/'
 tr a-z A-Z | sed 'y/abcdefghijklmnopqrstuvwxyz/ABCDEFGHIJKLMNOPQRSTUVWXYZ/'
 tr -s ' ' | sed 's/ \+/ /g'
 tr -d '\012' | sed 'H;$!d;g;s/\n//g'
 wc -l | sed -n '$='
 uniq | sed 'N;/^\(.*\)\n\1$/!P;D'
 rev | sed '/\n/!G;s/\(.\)\(.*\n\)/&\2\1/;//D;s/.//'
 basename | sed 's,.*/,,'
 dirname | sed 's,[^/]*$,,'
 xargs | sed -e ':a' -e '$!N;s/\n/ /;ta'
 paste -sd: | sed -e ':a' -e '$!N;s/\n/:/;ta'
 cat -n | sed '=' | sed '$!N;s/\n/ /'
 grep -n | sed -n '/patt/{=;p;}' | sed '$!N;s/\n/:/'
 cp orig new | sed 'w new' orig
 hostname -s | hostname | sed 's/\..*//'


To be reworked:

 echo 'Hi!' | sed 's/.*/Hi!/;q' <(yes)


NOTE: On MSDOS, use " instead '
