Not able to remove leading spaces
Hi Experts,

In a file tht i copied from the web , i am not able to remove the leading white spaces. I tried the below , none of them working . I opened the file through vi to check for the special characters if any , but no such characters found.
Your advice will be greatly appreciated.
Code:
sed 's/^\s*//g' file_name.txt

sed 's/^[ \t]*//g' file_name.txt

sed 's/^[ \t]*//'  file_name.txt

sed 's/ //g' file_name.txt

if you have Python
Code:
#!/usr/bin/env python
for line in open("file"):
  line=line.strip()
  print line

With sed:

Code:
sed 's/^ *\([^ ]*\)*/\1/' file

Probably you have leading spaces and tabs, try this one:
Code:
sed 's/^[     ]*\([^     ]*\)*/\1/' file

Within the character classes [] you have to type a space and a tab. Type <Ctrl-v> <tab> for the tab character.
