Make variables uppercase in bash.

Author	All Replies
Maxo Your tax dollars at work. Premium,VIP join:2002-11-04 Tallahassee, FL clubs: ·Embarq	Make variables uppercase in bash. I am trying to take part of a string and make it uppercase. For example: `export var='abcdefg' echo ${var:2:1}` With the exception that I need this to return 'C', not 'c'. The only thing I have been able to find are commands that take a whole file as a parameter and makes it all uppercase. Can anyone help me do this please?

Maxo Your tax dollars at work. Premium,VIP join:2002-11-04 Tallahassee, FL clubs: ·Embarq	I think I may need to be a little more specific. We are writing a bash script that reads some stuff and builds a control file for Oracle's sqlldr, and then we execute sqlldr with the build control file. Our code looks much like this: if [ "${LINE}" = "amico.990120" ]; then echo Building amic control file for ${LINE} echo LOAD DATA > file_loader.ctl echo INFILE \'${LINE}\' >> file_loader.ctl echo APPEND >> file_loader.ctl echo INTO TABLE schema.table >> file_loader.ctl echo "(" >> file_loader.ctl echo " column1(1:2)," >> file_loader.ctl echo " column2(3:4)," >> file_loader.ctl echo " column3 CONSTANT '" ${LINE:4:1} \| tr 'a-z' 'A-Z' "'," >> file_loader.ctl echo ")" >> file_loader.ctl sqlldr user/pass@database file_loader.ctl log=sqlldr.log silent=FEEDBACK else echo No Amic file found fi done < myAmicFiles The myAmicFiles just looks like this: amici.990120 amici.990220 amico.990520 amico.990620 I need the i or o to be uppercase. -- "Padre, nobody said war was fun now bowl!" - Sherman T Potter »www.cafepress.com/maxolasersquad »maxolasersquad.com/ »maxolasersquad.com/network/ My DSL Network Guide »myspace.com/mlsquad

deblin Dark Side of the Moon Premium,MVM join:2001-09-01 Middletown, DE ·Verizon FIOS ·Comcast Workplace ·DSL EXTREME	reply to Maxo So in this line: quote: echo " column3 CONSTANT '" ${LINE:4:1} \| tr 'a-z' 'A-Z' "'," >> file_loader.ctl You want just the capital letter? E.g. for LINE = amico.990120 you want just the O? Or do you want amicO.990120 ? -- He who is not contented with what he has, would not be contented with what he would like to have. -Socrates

deblin Dark Side of the Moon Premium,MVM join:2001-09-01 Middletown, DE ·Verizon FIOS ·Comcast Workplace ·DSL EXTREME	reply to Maxo Probably the easiest thing to do would be to set a variable for the letter first, then just use that variable. e.g instead of: bash code: echo " column3 CONSTANT '" ${LINE:4:1} \| tr 'a-z' 'A-Z' "'," >> file_loader.ctl try: bash code: the_char=`echo ${LINE:4:1} \| tr a-z A-Z` echo " column3 CONSTANT '$the_char'," >> file_loader.tcl Again, assuming you just want the O there and not the full name. If you want the full name, it'd be slightly more involved but not terribly so. -- He who is not contented with what he has, would not be contented with what he would like to have. -Socrates

Sir Meowmix III @windstream.net	reply to Maxo Agree, good call, at that point the regex would be positional on the file extension.

Maxo Your tax dollars at work. Premium,VIP join:2002-11-04 Tallahassee, FL clubs: ·Embarq	reply to Sir Meowmix III I've never used sed before and have only recently began reading up on regular expressions. I read through the man pages and looked at the code you gave. It appears to work with the following code: echo $LINE \| sed 's/o\./O\./g' \| sed 's/i\./I\./g' The only thing that is missing is how to take the result of this output and store it in a variable. -- "Padre, nobody said war was fun now bowl!" - Sherman T Potter »www.cafepress.com/maxolasersquad »maxolasersquad.com/ »maxolasersquad.com/network/ My DSL Network Guide »myspace.com/mlsquad

Maxo Your tax dollars at work. Premium,VIP join:2002-11-04 Tallahassee, FL clubs: ·Embarq	said by Sir Meowmix III : [code] MYVAR=$(echo $LINE \| sed 's/o\./O\./g' \| sed 's/i\./I\./g') echo $MYVAR [/code] That did it. Thanks a lot. You can probably tell that we just started learning how to write these scripts a few weeks ago.
