sed command within script wrongly deleting the last line
Hi,
I have a shell script which has a for loop that scans list of files and do find and replace few variables using sed command. While doing this, it deletes the last line of all input file which is something wrong. how to fix this. please suggest. When i add an empty line in all my input file, it fixes the issue. but i look for any other suggestion that will avoid adding this empty line.
my code snippet is:
where i - is the input file
tilda_var1 - is the pattern to be replaced
tilda_value - is the final string will go in place of variable tilda_var1

Hi there,
I'd like to delete the beginning of a line up until it finds a certain word or character string: in this case, I'd like to delete each line up to the word "mounting".
Thanks ;)

supposed to delete a line starting with '3' and then append 'text' after the last line of input. But, if it is the last line of input which starts... (2 Replies)

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
