mierdatuti · 07-30-2015, 09:14 AM

Hi,
I have a rtf file and I would like to match a pattern with grep but doesn't works. Maybe because is a rtf file?

The file have:

Code:

.....
\langfenp3082 {\rtlch\fcs1 \af0 \ltrch\fcs0 
\cs17\lang1033\langfe3082\super\langnp1033\insrsid9076107\charrsid9076107 $}{\rtlch\fcs1 \af0 \ltrch\fcs0 \lang1033\langfe3082\langnp1033\insrsid9076107\charrsid9076107  }{\rtlch\fcs1 \af39 \ltrch\fcs0 
\f39\lang1033\langfe3082\langnp1033\insrsid9076107\charrsid9076107 job_dataservices_0000}{\rtlch\fcs1 \af39 \ltrch\fcs0 \f39\lang1033\langfe3082\langnp1033\insrsid9076107 7}{\rtlch\fcs1 \af39 \ltrch\fcs0

If I do :

Code:

grep -i "\\ltrch\\fsc0" file.rtf
or
grep -i "\ltrch\fsc0" file.rtf

--

No ocurrences

One of these things is not like the other.

The subtle difference here is schneidz' use of single quotes versus double quotes around the regular expression.

I admittedly was a bit confused why that was posted, it almost seemed like a reiteration of the problem but it is an example of the solution.

\backslash\ is a special character for grep, so you have to duplicate it:

Code:

grep -i "\\\\ltrch\\\\fsc0" file.rtf
or
grep -i '\\ltrch\\fsc0' file.rtf
