I have searched and found various threads about removing spaces from a field within a text file. Unfortunately, I have not found exactly what I'm looking for, nor am I adept enough to modify what I've found into what I need.
I use the following command to remove the first line from a text file (the column headers): sed 1d file > file2
I then want to strip the leading spaces from the first field only, but so far, all I can do is the following: cat file2 | awk '{print $1}' > file3
That successfully strips the spaces, but only gives me that one field. Since the number of fields could vary from day to day (an updated field is received every night, and additional fields are often added), how can I modify that script to ensure all fields are written to the new file with the spaces stripped only from the first field?
Excellent. Can I ask for one step further? Can you correct my syntax for a one-liner that will remove the leading spaces from every field? I have some db fields that specify for char of 9, but then they have only 6 or 7 characters within the field, so it fills in the extra spots with spaces. There are a few fields that I've had to script around to deal with this.
For the sed 's/^ *//' /path/to/file > /path/to/newfile, It looks as though this: /^ */ specifies the beginning of the line, and the 's means space, so I understand that it is stripping the spaces from the beginning of the line. The next problem I found is that a field further down in the list of fields may also need the leading spaces stripped. Problem is, the field number may change as more fields are added/removed, so I don't know what the field number will be on any given day - better to just strip 'em all.
Is there a way using the sed command to strip all leading spaces from all fields?
