Full Discussion: deleting blank space in beginning of line in vi
Operating Systems Solaris deleting blank space in beginning of line in vi Post 302354896 by varontron on Sunday 20th of September 2009 09:29:21 PM

To delete blank spaces at the start of lines 7 thru 21:

Code:
:7,21s/^ +//

That's [colon seven comma two one s slash carot space plus slash slash]

To do it on every line:

Code:
:%s/^ +//

That's [colon percent s slash carot space plus slash slash]

Colon = command mode
numbers or % = lines to edit
s = substitute
slashes separate pattern and replacement strings
carot = start of line
space = actual space
plus = one or more
2 slashes = empty replacement string = delete

hth,
dv

basename

BASENAME(1)						    BSD General Commands Manual 					       BASENAME(1)

NAME

     basename, dirname -- return filename or directory portion of pathname

SYNOPSIS

     basename string [suffix]
     basename [-a] [-s suffix] string [...]
     dirname string

DESCRIPTION

     The basename utility deletes any prefix ending with the last slash '/' character present in string (after first stripping trailing slashes),
     and a suffix, if given.  The suffix is not stripped if it is identical to the remaining characters in string.  The resulting filename is
     written to the standard output.  A non-existent suffix is ignored.  If -a is specified, then every argument is treated as a string as if
     basename were invoked with just one argument.  If -s is specified, then the suffix is taken as its argument, and all other arguments are
     treated as a string.

     The dirname utility deletes the filename portion, beginning with the last slash '/' character to the end of string (after first stripping
     trailing slashes), and writes the result to the standard output.

EXAMPLES

     The following line sets the shell variable FOO to /usr/bin.

	   FOO=`dirname /usr/bin/trail`

DIAGNOSTICS

     The basename and dirname utilities exit 0 on success, and >0 if an error occurs.

SEE ALSO

     csh(1), sh(1)

STANDARDS

     The basename and dirname utilities are expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
