Replacing string with awk
I am trying to replace Code:
javascript:top.showarticle('geo',1985,'with Code:
../../abstracts/geo1985/ I am using awk but getting an error Code:
awk -v s="javascript:top.showarticle('geo',1985,'" -v d="../../abstracts/geo1985/" '{gsub(s,d); print} ' geo50n12.html > geo50n12.html.tmpFixed it using Code:
awk -v s="javascript:top.showarticle\('geo',1985,'" -v d="../../abstracts/geo1985/" '{gsub(s,d); print} ' geo50n12.html > geo50n12.html.tmp---------- Post updated at 02:44 PM ---------- Previous update was at 01:18 PM ---------- I also want to replace Code:
','geo with /geo and Code:
',0) with .pdf I have tried using the following but is not working Code:
awk -v s=$src -v d=$dst '{gsub(s,d); gsub("','geo","/geo"); gsub("',0)",".pdf"); print}' $f > $ftmpLast edited by kristinu; 04-07-2012 at 03:41 PM.. |

s="$src" and
d="$dst" need double quotes s, being the first part in the sub function is not a string but an extended regular expression. As such special characters need to be escaped, with 4 backslashes: Code:
src="javascript:top.showarticle\\\\('geo',1985,'"Alternatively you could use this: Code:
src="javascript:top.showarticle[(]'geo',1985,'" Technically a . means "any character" so in theory that would need to be escaped, but in practice that will probably not be necessary.. Last edited by Scrutinizer; 04-07-2012 at 05:02 PM.. |

One thing at a time I am writing the commands to a file, called Code:
commands.run and then run everything using ./commands.run So I need to print the command. I am doing this using Code:
set year = "1985"
echo "awk -v s="javascript:top\.showarticle[(]'geo',${year},'" -v d="../../abstracts/geo${year}/" '{gsub(s,d); print}' $f > $ftmp" >> $frunHow can I introduce the " in the file? ---------- Post updated at 05:04 PM ---------- Previous update was at 04:13 PM ---------- I am now just trying to do the command: Quote:

I think the problem is here: Quote:
It should be: Code:
year=1888 (no spaces around the = ) |
