bash script to remove first characters from every line

(00) · 01-25-2008, 09:19 AM

I downloaded bazaar.txt for a shell scripting-pdf, so that I can follow the examples I want to get rid of the margin (there are two spaces in front of every line. I've tried

sed '/^ /!d' bazaar.txt | tr -s ' ' > bazaar2.txt

but this will only remove one space, one more to go

using the same method btw does not work twice. Hints, links, information and flames all appreciated.

To cut off a range of characters you can do:

Code:

cut -b 1-2 --complement bazaar.txt

This cuts off the range of '1-2' or in this case the range from 1 to 2 characters inclusive (the first two characters). For example it would be 5-23 if you wanted to cut off characters 5 to 23 inclusive.

-It's funny, I'm doing this so I have a file to work with to learn shell-scripting(shell-scripting.pdf)...and to get passed the 'sed' and 'tr' lessons, 'cut' would have been next! Anyway thanks texmex

sed 's/^ *//' file > newfile

Removes any number of spaces at the beginning of the line

HI
I'm also trying to wade throught the shellscripting.pdf book but am unable to find the files it refers to in the examples. Both the bazaar.txt and emails{1,2,3}.txt.

COuld you tell me where you obtained them from?

Hi,

Can you please let me know where to download the files listed in shell-scripting.pdf? http://www.catb.org/~esr/writings/cathedral-bazaar/ does not work. I also not able to download other files, emails1.txt, emails2.txt emails3.txt columns.txt telnum.txt. I would really appreciate if someone can tell me where to get these files.

Thanks,
Mak

I'm trying to combine two text files and remove common phrases in each file. I've done that with
'comm -3 text1.txt text2.txt > new.txt'
But it puts them in columns so I have a column for text1 and a column for text2 so I did
'comm -3 --output-delimiter=0 text1.txt text2.txt > new.txt'
but now I have 0's in front of text2 phrases. I was wondering if there was anything I could && or | to, to remove the 0's or maybe even a better way of doing this. I would greatly appreciate any nudges in the right direction.

Try using 'uniq -u' instead.

I ended up using

Code:

cat ~/txtfolder/* |sort|uniq|less > new.txt

so essentially the same just added a couple, thanks though.
