Hello,
Could someone help me with sed. I have searched for solution 5 days allready , but cant find. Unfortunately my "sed" knowledge not good enough to manage it. I have the text:
Code:
123, foo1, bar1, short text1, dat1e, stable_pattern
124, foo2, bar2, long text
with few
lines, date, stable_pattern
125, foo3, bar3, short text2, date, stable_pattern
I need 1 string per record. So, 124 record should be ammended and all its lines should be joined in one. Output should be:
Code:
123,foo, bar,short text,date,stable_pattern
124,foo2, bar2, long text with few lines,date, stable_pattern
125,foo3,bar3,short text, date, stable_pattern
Actually i need to join lines that do not match pattern. In this sample pattern is "stable_pattern". I "construct" the following command, but it does not work:
Code:
cat text|sed -e '/stable_patter/!s/$//'
Seams the way is correct, but it does not remove the |new line| symbol:
Code:
cat text|sed -e '/stable_patter/!s/$/_______sould_be_removed_____/'
123, foo1, bar1, short text1, dat1e, stable_pattern
124, foo2, bar2, long text_______sould_be_removed_____
with few_______sould_be_removed_____
lines, date, stable_pattern
125, foo3, bar3, short text2, date, stable_pattern
Somewhere on the internet i found another example, but it does not work for me too:
Code:
cat text|sed -e ":a;N;/stable_pattern/!s/\n//g;ta"
123, foo1, bar1, short text1, dat1e, stable_pattern
124, foo2, bar2, long text
with few
lines, date, stable_pattern
125, foo3, bar3, short text2, date, stable_pattern

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).
