@Hammadi dali,
No man, its not working..
See
Yes by using your script,
E.g
echo " sdfsdf" | sed 's/^ /zzz/g'
Then the o/p is zzzsdfsdf.
But for example if a file contains content as follows,
181 last
182 first
183 begin
184 apropos lst
185 lstat
186 stat
187 apropos last
188 lastcomm
189 dir
190 lastcomm
191 lastlog
192 errno
193 last
Now i want to remove first 7 characters from all the lines whether it is space or number.
I tried this one
sed -e "s/.//1" -e "s/.//1" -e "s/.//1" -e "s/.//1" -e "s/.//1" -e "s/.//1" -e "s/.//1" linuxcommands.sql >xxx.sql
The above command replaces first 7 characters from all the lines of the file..
But still i am thinking to achieve this in some other way.
If u came to know some other process to arrive at this solution means,
Reply me.

Hi,
In the vi editor, I could do a search and replace:
:%s/work/play/g
but how do I do this for a string/text with space? like if I want to replace all text of "come here" with text "go there"? I've tried with quotes, double quotes, back slash, none of them worked.
thanks!... (1 Reply)

PR(1) General Commands Manual PR(1)
NAME
pr - print file
SYNOPSIS
pr [ option ... ] [ file ... ]
DESCRIPTION
Pr produces a printed listing of one or more files on its standard output. The output is separated into pages headed by a date, the name
of the file or a specified header, and the page number. With no file arguments, pr prints its standard input.
Options apply to all following files but may be reset between files:
-n Produce n-column output.
+n Begin printing with page n.
-b Balance columns on last page, in case of multi-column output.
-d Double space.
-en Set the tab stops for input text every n spaces.
-h Take the next argument as a page header (file by default).
-in Replace sequences of blanks in the output by tabs, using tab stops set every n spaces.
-f Use formfeeds to separate pages.
-ln Take the length of the page to be n lines instead of the default 66.
-m Print all files simultaneously, each in one column.
-n Number the lines of each file.
-on Offset the left margin n character positions.
-sc Separate columns by the single character c instead of aligning them with white space. A missing c is taken to be a tab.
-t Do not print the 5-line header or the 5-line trailer normally supplied for each page.
-wn For multi-column output, take the width of the page to be n characters instead of the default 72.
