UNIX for Dummies Questions & Answers

Hi There!

I've got a tab delimited text file (output from a software) to which I would like to delete specific strings from one of the columns. I have tried several sed codes, but they do not seem to work for me. I can manage to delete a specific word, but this is of no use, as I what I want to do is analogous to a e.g., "rm *jul10" to delete all files that start with "jul10" in a unix terminal. I have tried this code:

Code:

sed -e 's/c\w+//g' editfile.txt > editfile2.txt   #where c is the first character of the string you would like to delete (i followed a previous thread on this)

but it has not work. Something is printed on the terminal, but the output file is unmodified.

All help is welcome! Thanks!

put sample input log and output you expect.

try like this

Code:

 
# sed -e 's/c\w\+//g' editfile.txt > editfile2.txt

Thanks for the input.

Code:

sed -e 's/c\w\+//g' editfile.txt > editfile2.txt

left the output file completely unchanged, which I find a bit bizarre. Any clues as to why this is happening?

Thanks.........

I got this to do the job, which deletes the number of characters equivalent to the number of dots after the "i" character.

Code:

sed -e 's#.i..............##g' fraglist2.txt > fraglist3.txt

I would like to get ygemici's command working. Seems a lot more versatile...Thanks!
