List only directories, one per line

Normally, if you just want to see directories you'd use brianmuckian's command 'ls -d *\', but I ran into problems trying to use that command in my script because there are often multiple directories per line. If you need to script something with directories and want to guarantee that there is only one entry per line, this is the fastest way i know Show Sample Output

looking for files not subversioned

En entornos de desarrollos muchas veces se mezclan ficheros y debemos revisar si algo se nos ha quedado fuera del proyecto. Con esta linea de comando busco todos los ficheros que no sean M ( modificados ) para valorar si tengo que agregarlo al repositorio de subversion. Adem?s siempre se me olvida como usar un condicional con awk para una columna :D

Even shorter: $ seq -s '*' 120|tr -d '[0-9]'

Pimp your less

# s = combine multiple lines of whitespace into 1 # x4 = set the tabstop to 4 instead of 8 # F = Exit if the output fits on 1 screen. This is similar to git diff # R = Raw control chars. This allows you to pipe colordiff straight to less. ie: alias sdi="svn diff | colordiff | less" # S = Chop off long lines # X = Dont send termcap init and deinit scrings to the terminal
