It's possible to do stream editing (SED) on one line by using the semi-colon.
It might speed up the script as well.
| Code: |
sed -i "s%<b>%%g;" /tmp/report-video_
sed -i "s%</b>%%g" /tmp/report-video_
sed -i "s%<b>%%g;s%</b>%%g" /tmp/report-video_

Hello don570,
Yes, it is much better! This is the way we learn, little by little... Thank you! I will have to revise most of the scripts I made, because since the first one, I learnt many small tricks like this one: for sure, they will be less heavy and faster! 
Cordialement.

Bonjour,
Following the code lines above, I replaced: | Code: | func () {
sed -i "s%<b>%%g" /tmp/report-video_
sed -i "s%</b>%%g" /tmp/report-video_
sed -i "s%millimeters%$(gettext 'millimeters')%g" /tmp/report-video_
sed -i "s%planes%$(gettext 'planes')%g" /tmp/report-video_
sed -i "s%pixels%$(gettext 'pixels')%g" /tmp/report-video_
}
export -f func
sed -i "s%millimeters%$(gettext 'millimeters')%g" /tmp/report-video
sed -i "s%planes%$(gettext 'planes')%g" /tmp/report-video
sed -i "s%pixels%$(gettext 'pixels')%g" /tmp/report-video |
with: | Code: | func () {
sed -i "s%<b>%%g";"s%</b>%%g";"s%millimeters%$(gettext 'millimeters')%g";"s%planes%$(gettext 'planes')%g";"s%pixels%$(gettext 'pixels')%g" /tmp/report-video_
}
export -f func
sed -i "s%millimeters%$(gettext 'millimeters')%g";"s%planes%$(gettext 'planes')%g";"s%pixels%$(gettext 'pixels')%g" /tmp/report-video
|
And I got:
| Quote: | sed: no input files
/usr/sbin/2P_report-video: line 127: s%planes%niveaux%g: command not found
/usr/sbin/2P_report-video: line 127: s%pixels%pixels%g: command not found
sed: no input files
sh: line 1: s%</b>%%g: No such file or directory
sh: line 2: s%millimeters%millimètres%g: command not found
sh: line 3: s%planes%niveaux%g: command not found
sh: line 4: s%pixels%pixels%g: command not found
EXIT="OK"
Script completed hit RETURN to close window. |
 
Cordialement.

The syntax is like this:
| Code: | sed -i -e '....' -e '...' filename
|
or:
| Code: | sed -i -e '....' \
-e '...' \
-e '...' filename
|

Pas exactement du tout! Sorry! | Code: | func () {
sed -i "s%<b>%%g;s%</b>%%g;s%millimeters%$(gettext 'millimeters')%g;s%planes%$(gettext 'planes')%g;s%pixels%$(gettext 'pixels')%g" /tmp/report-video_
}
export -f func
sed -i "s%millimeters%$(gettext 'millimeters')%g;s%planes%$(gettext 'planes')%g;s%pixels%$(gettext 'pixels')%g" /tmp/report-video |
As we are used to say in French: "I had no eyes in front of holes"
This is very much better this way! 
Thank you!
Cordialement.
